Many have been asking for what i need to check to make sure SCCM is healthy. According to me if I were you these are things I would have checked :)

This might not be complete but had tried to include what ever I could think of.

 

Administrative Activities: 

 

Daily Administrative Task

 

Daily Site Monitoring Tasks

To best maintain your system, perform the following monitoring tasks on a daily basis. If there is any indication of a problem, isolate and repair the problem to ensure that the site remains healthy.

Daily site monitoring tasks include:

  • Checking SCCM site database status.
  • Checking site server status.
  • Checking site systems status.
  • Checking client status.
  • Checking the operating system event log.
  • Checking the SQL Server error log.
  • Checking system performance.
  • Checking SCCM system folders.

 

Check SCCM Site Database Status

Use the SQL Server DBCC command to check the health of the SCCM site database. Use any other tools available to test the health of the SCCM site database.

 

Check Site Server Status

View site status summary information in the SCCM Administrator console, or create reports that summarize the server activity and status (such as the Clients that Received a Specific Advertised Program report). If necessary, check status messages of individual components. For further details, in case status messages indicate that a problem exists, view the relevant log files. Isolate and fix conditions that generate errors or warnings. If appropriate, reconfigure the status system so that only relevant and helpful messages are recorded.

Check the status of items such as:

  • Site components and services. Check if any site server component or service is experiencing any problems.
  • Packages and advertisements. Check the status of packages and advertisements in your site. Check package and advertisement status messages to ensure that package source files reach distribution points, and that advertised programs reach clients. Check status messages that are returned from clients to see whether the clients run programs successfully or not.
  • Site-to-Site Communication. Check communication between the site and its parent and child sites (if they exist). Check status messages and, if necessary, check log files of the Replication Manager, Scheduler, and Senders on the site to determine whether the site is having communication problems.

 Check Site Systems Status

Check the state of site systems throughout the SCCM hierarchy. Use the status system and, if necessary, use log files to determine if site systems are having problems, such as:

  • Low level of available disk space.
  • SCCM components that cannot connect with a site system.

Check Clients Status

Check the state of clients in the hierarchy. Run queries on status messages to detect any problems that clients might be having, such as:

  • Client components are experiencing problems.
  • Clients are failing to install.
  • Clients are not reporting software inventory or hardware inventory.
  • Clients that are not reporting heartbeat discovery data regularly (or for the past x days).
  • Client count unexpectedly increasing or decreasing at a fast rate.

You can monitor a client's status only if it creates status messages, and these status messages reach the site server.To detect clients from which you are missing status messages, you need to run a query that returns all clients that have not reported a status message within the last <n> days. In this query, <n> is the length of time you would expect to receive a status message from that client (taking into account the frequency of hardware or software inventory and the regular time it takes for status messages to reach the site server.)

 

Check the Operating System Event Log

On key servers, check the application, system, and security system event logs. You can access those through the Event Viewer administrative tool. Look for messages that indicate error conditions or developing problems. Isolate and repair the conditions that generate error or warning messages.

When installing an SCCM site server, its default configuration is to write status messages to the event log. This helps you identify any developing problems with SCCM.

Note :When SCCM is configured to write status messages to Windows event logs, SCCM error status messages are written as Information events, not Error events.

Save instances of the most recent event log files for future comparison. When you can compare current log files with previous log files, it is easier to detect problems that are developing. After saving the log files, you can clear them from the event log so it is easier to detect new problems.

 

Check the SQL Server Error Log

Check the SQL Server error log in SQL Enterprise Manager. Look for messages that indicate error conditions. Isolate and repair the conditions that generate error or warning messages.

 Check System Performance

To check whether the site server and component servers have sufficient resources and that SCCM site services are running optimally, you must monitor site server and component server performance. Use performance-monitoring tools such as System Monitor in the Performance console. Check the status of critical components on the site server, on the computer running SQL Server, and other SCCM site systems.

SCCM installs many performance monitor counters, but you can add, remove and configure counters as needed. You can also use the SQL Server performance counters.

Save performance log files for future comparison. It is easier to detect performance trends, and to identify potential bottlenecks, when comparing current performance log file to previous performance log files.

 

Check Status Filter Rules

Check whether it is possible to reduce the amount of traffic generated by status messages being replicated throughout the hierarchy. If the site is currently healthy, it might be possible to add status filter rules to prevent replication of status messages, which are not necessary.

 

Check the Inboxes to Monitor

 

Listed here is a list of the ConfigMgr 2007 inboxes that should be checked on a regular basis to ensure that your site(s) function as expected.
Auth\Dataldr.Box : A backlog of files can indicate problems accessing the site database.

Check Daily Maintenance Task

 

Check and make sure that the daily Maintenance Task if any. We can use the smsdbmon.log for more details.

 

 

Weekly Administrative Task

 

Weekly Site Monitoring Tasks

To best maintain your system, perform the following monitoring tasks on a weekly basis. If there is any indication of a problem, isolate and repair the problem, to ensure that the site remains healthy.

Weekly site monitoring tasks include:

  • Checking SCCM site database available space.
  • Checking available disk space.

Check SCCM Site Database Available Space

To find the amount of space used by database devices, run the SQL Server stored procedure sp_spaceused against the SCCM site database. For more details about sp_spaceused, see the SQL Server Help. Check the tempdb device at peak usage, when several instances of the SCCM Administrator console are using the database and the site is actively processing objects.

 Check Available Disk Space

Check the amount of available disk space on the site server, the SCCM site database server, and other SCCM servers. Ensure that the amount of free disk space is sufficient for SCCM and SQL Server to perform properly during regular and increased activity load.

To use the Status System to view information about site system disk space

  1. In the SCCM Administrator console, navigate to Site System Status.

Configuration Manager > Site Database > System Status> Site Status> <site name>> Site System Status

  1. In the details pane, view status information of site systems such as free disk space.

 

Weekly Site Maintenance Tasks

To best maintain your system, perform the maintenance tasks in this section on a weekly basis. You can automate some tasks by scheduling predefined maintenance tasks or custom maintenance tasks, as appropriate, to run on a weekly basis.

 

Weekly site maintenance tasks are:

  • Weekly automated tasks.
  • Delete unnecessary files.
  • Delete unnecessary SCCM objects.
  • Produce and distribute end-user reports.
  • Run disk defragmentation tools.
  • Back up application, security, and system event logs.

 Weekly Automated Tasks

The following predefined maintenance tasks should be scheduled to run on a weekly basis. For more information about these tasks, see the "Predefined Site Maintenance Tasks" section earlier in this chapter.

  • Rebuilding Indexes
  • Monitor keys
  • Delete aged inventory history
  • Delete aged discovery data
  • Delete aged collected files
  • Delete aged software metering data
  • Delete aged software metering summary data
  • Summarize software metering data
  • Summarize software metering periodic usage data

Delete Unnecessary Files

If Management Information Format (MIF) files or IDMIFs are used to extend hardware inventory in your site, then any MIF files that are not valid are placed in the SCCM\inboxes\dataldr.box\BADMIFS folder and SCCM never removes them. You must empty this folder manually. If a large number of MIFs are placed in the BADMIFS folder, it is likely that a MIF generating tool is producing the MIFs with an incorrect format. Investigate and repair the cause of the bad MIFs.

 Delete Unnecessary SCCM Objects

Delete objects such as collections, queries, and packages that are no longer needed at the site. Deleting unnecessary objects saves disk space, reduces intersite replications, and increases performance.

Caution :When deleting a collection, any advertisements to that collection are also deleted.

 Run Disk Defragmentation Tools

Over time, disk volumes on SCCM site systems become fragmented. Site operations such as distributing large software packages might significantly increase fragmentation on site servers and distribution points. As fragmentation increases, disk operations take longer, thus, the overall site performance decreases.

Run disk defragmentation tools on the SCCM site server and all other site systems to maintain the performance level of disk operations.

 Back Up Application, Security, and System Event Logs

Windows event logs can get full, and by default, new items will start to overwrite older items. To diagnose problems, and for other reasons, it might be necessary to refer to an older event log. It is recommended that you back up Windows event logs, and store the backups in a safe and accessible location. If necessary, increase default logs file size to accommodate larger amounts of data.

 

 

Periodic Administrative Task

 

Periodic Site Maintenance Tasks

To best maintain your system, perform the following tasks periodically. Use the predefined maintenance tasks when appropriate.

Periodic site maintenance tasks include:

  • Backing up account data.
  • Changing accounts and passwords.
  • Checking network performance.
  • Reviewing the security plan.
  • Reviewing the maintenance plan.
  • Performing recovery tests.

Back Up Account Data

To properly recover a site server, you must have information about the accounts that SCCM used before the site failed. Account data is stored in domain controllers.

Use Microsoft tools, such as the NTBackup.exe tool that comes with Windows Server, or third-party tools to back up account data as follows:

 

  • If there are multiple domain controllers in your infrastructure that contain the SCCM account database, you need to periodically back up the account database. (If Active Directory® directory service is implemented in your organization, then such a task might be included in the Active Directory maintenance plan.)
  • If the account database is stored on a single domain controller, then back up the account database frequently. Depending on the frequency of changes to account data, you might need to add this task to the site's daily or weekly maintenance tasks.
  • If the account data is stored on member servers, then regularly back up the whole operating system that contains the account data, using software that backs up account lists and the account database.
  • Whenever there is a change to the password of the Client Push Installation account or to the site system connection accounts, you should note that change. For security reasons, SCCM  encrypts the Client Push Installation account and the site system connection accounts. You need to be able to retrieve these accounts' passwords so that you can re-enter them during a site recovery operation.
  • In between account database backups, document any changes to accounts. Write down and save any changes made to SCCM accounts and share rights so that you can apply those changes again after recovering the site.

 

Change Accounts and Passwords

To maintain the level of security in your hierarchy, you must periodically change the passwords and the accounts that SCCM sites use. Report any changes to the security staff so that security administrators know that these changes are planned and authorized.

To develop an effective security maintenance plan for your SCCM hierarchy, you must thoroughly understand how security is deployed in your hierarchy and make the following decisions:

 

  • Which accounts need to be changed, and for which accounts is it sufficient to change only the password.
  • How often to change passwords and accounts.
  • How to change passwords and accounts (such as by running SCCM site reset).
  • Which accounts cannot be configured by the administrator (either the account name cannot be changed, or the password cannot be manually modified).

 Check Network Performance

Check the available bandwidth and error rates on the networks used by the SCCM hierarchy. Use Network Monitor to capture and analyze network frames so you can diagnose network problems and look for optimization opportunities.

 Review the Security Plan

SCCM evolves with time. User roles change, and people might no longer need access to some or any of the SCCM functions. Although most changes in access permission should be implemented after role or staff changes, you should also periodically review the access for all users or groups to identify and delete unauthorized access permissions.

The security plan implemented for the SCCM hierarchy in your organization needs to support the risk assessment of your organization. As your organization changes, policies can become ineffective.

Review security-related settings such as:

  • Who has access to SQL Server and to the SCCM site database.
  • Who can download from SCCM distribution points.
  • Which accounts have permissions within SCCM security.
  • Periodically, re-evaluate the risk assessment of your organization, and then review and update the security plan accordingly.

 Review the Maintenance Plan

Use the maintenance plan document to review the SCCM maintenance plan. SCCM evolves with time, and it might be necessary to adjust the maintenance plan to accommodate growth, development, and other changes in your organization.

If there were any changes in your organization's security strategy, backup and recovery strategy, or any other strategy that affects SCCM, then determine if the maintenance plan needs to be adjusted to reflect these changes.

Review maintenance tasks configuration. Check the amount of data in the site database and evaluate the usefulness of that data against the amount of space that it occupies in the database. If necessary, adjust the settings that determine the number of days that data is retained in the database.

 

Update the maintenance plan document to reflect any changes to the maintenance plan, and then distribute it to all SCCM administrators that are using it.

 Perform Recovery Tests in a Test Lab

 The best way to be fully prepared for a site recovery operation is to ensure that the recovery plan is adequate and that administrators are familiar with the recovery process. After you develop a recovery plan for your site, it is recommended that you perform periodic recovery tests in a test lab.

A recovery test should follow the recovery plan developed for the production environment. Plan to perform a recovery test of the central site, and of any other systems deployed in your hierarchy. A recovery test should test all phases of recovery, including:

  • Backing up a site.
  • Archiving the backup snapshot.
  • Simulating a site failure, such as by turning a server off.
  • Recovering the failed site.
  • Verifying the success of the recovery operation.
  • You might schedule periodic recovery tests. Company policy might require that new administrators always perform a recovery test. It is strongly recommended that you always include a recovery test when testing major changes to the hierarchy.
  • For example, before upgrading site server operating systems, you should probably first test the upgrade in the test lab. After completing the upgrade in the test lab, you should perform a recovery test to identify any issues or adjustments to the recovery plan associated with the operating system upgrade. This ensures that if you upgrade the servers in the production environment, you will still be able to successfully recover a failed site.
  • Include a recovery test in every major deployment test, such as:
  • A major operating system upgrade (not service pack).
  • A major change to the networking infrastructure.
  • New equipment deployment or building relocation.
  • An SCCM major version site upgrade.

 

Periodic Site Monitoring Tasks

To best maintain your system, perform the following monitoring tasks periodically. If there is any indication of a problem, isolate and repair the problem to ensure that the site remains healthy.

Periodic site monitoring tasks include:

  • Checking hardware.
  • Checking site's overall health.
  • Checking the backup snapshot.

 

Check Hardware

Even high-quality hardware occasionally fails. Sometimes, it fails gradually, so there might be early signs. Replacing hardware before it completely fails is a key step in preventing site failure. Both Windows and SCCM provide performance counters, which you can use to monitor the performance and state of the hardware used in the site.

As soon as you notice any signs of hardware-related unreliable behavior of an SCCM server, replace the hardware. To properly replace server hardware, you must use the Recovery Expert. For more information about swapping the computer of SCCM servers, see the "Swapping the Computer of a Site Server" section later in this chapter.

 Check Site's Overall Health

It is recommended that you periodically perform a more thorough health check, as follows:

  • Ensure that all SCCM services are running.
  • Review the Status Message System for Critical status.
  • Ensure that all the latest service packs are installed.
  • Ensure that the latest critical security patches are installed.
  • Examine the System and Application Event logs for errors.
  • Note
    • When SCCM is configured to write status messages to the system's event log, SCCM error status messages are written as information events, not error events.
  • Run a query to determine if discovery data is being updated correctly in the SCCM site database. The query should list all installed clients in which System Resource - Agent Time is not within the heartbeat interval. It is expected that some clients might be offline, but in other cases, it might indicate a problem.
  • Run a query to determine if software inventory data is being updated correctly in the SCCM site database. The query should list all installed clients in which Last Software Scan - Last Inventory Collection is not within the software inventory interval. It is expected that some clients might be offline, but in other cases, it might indicate a problem.
  • Run a query to determine if hardware inventory data is being updated correctly in the SCCM site database. The query should list all installed clients in which Workstation Status - Last Hardware Scan is not within the hardware inventory interval. It is expected that some clients might be offline, but in other cases, it might indicate a problem.

If any of these tests fail, you need to diagnose the problem and repair it.

 Check the Backup Snapshot

At the end of every site backup cycle you should check the validity of the backup snapshot. Periodically, you should perform a more thorough check to ensure that the site's backup snapshots can be successfully used for recovery.

Restore a recent backup snapshot to a disk and examine file continuity, file size, and other file properties to ensure that they do not seem corrupted. Check critical files by restoring these files to their respective applications to ensure that the application can use the restored file.
