Delete cbs.log file its growing large

This post describes about cbs.log file which is growing large and how you can delete. System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. Run the System File Checker tool (SFC.exe) to scan your system files and to repair missing or corrupted system files. CBS.Log file is generated by the Microsoft Windows Resource Checker (SFC.exe).

The SFC.exe program writes the details of each verification operation and of each repair operation to the CBS.log file. The CBS.persist.log is generated when the CBS gets to be around 50 meg in size. CBS.log is copied to cbs.persist.log and a new cbs.log file is started.

Solution 1 :

you can try compressing the file:

Right click on the CBS.log file.
Click on Properties.
On the General tab, click Advanced.
Check “Compress contents to save disk space” and click on OK.

Solution 2 :

Another Workaround is to turn off unnecessary services that may calling into CBS;

To disable CBS log, you may change registry key in

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Component
Based Servicing] EnableLog=dword:00000000

In addition,also recommended to run sfc/scannow to check the health of system files.

Solution 3 :

If you are sure your system is running fine, you can delete this file. SFC.exe will create a new one, next time it is run.

Please follow below method to delete:

Stop TrustedInstaller.exe (Windows Module Installer) in Taskmanager Services tab. Additionally if you cannot, open the Taskmanager Processes tab and End Task the same process.
Delete or move all the .log files in the C:\Windows\Logs\CBS directory, you can delete the .persist and .cab files as well.
Start Windows Module Installer service (TrustedInstaller.exe) again

search diagnostics and reports sharepoint

Posted on 17/01/2017 by Deviprasad Panda

We can access and analyze several query and crawl health reports, logs and usage reports from the Search service application in the SharePoint Central Administration to monitor the health of the search system.

The health reports and logs only contain information after a full crawl has completed. To run a full crawl, we have to set up a Search service application, add at least one content source, and then start a full crawl.

To view the health reports and the crawl log, one have to be an administrator of the Search service application. Alternatively, an administrator who is a member of the Farm Administrators group can grant user accounts Read permissions on the Search service application. A user account that has Read permissions can only view the Search service application status page, the health reports and the crawl log.

Query health reports:

Trend
Overall
Main Flow
Federation
SharePoint Search Provider
People Search Provider
Index Engine

To view query health reports:

Verify that the user account that is performing this procedure is an administrator of or has Read permissions to the Search service application.
In Central Administration, under Application Management, click Manage service applications.
On the Service Applications page, click the Search service application.
On the Search Administration page, in the Quick Launch, in the Diagnostics section, click Query Health Reports.
On the Search Service Application: Query Latency Trend page, click the query report that you want to view.

The following table shows which reports are available.

Crawl health reports:

SharePoint 2013 provides the following reports about crawl health:

Crawl Rate
Crawl Latency
Crawl Queue
Crawl Freshness
Content Processing Activity
CPU and Memory Load
Continuous Crawl

To view crawl health reports

Verify that the user account that is performing this procedure is an administrator of or has Read permissions to the Search service application.
In Central Administration, under Application Management, click Manage service applications.
On the Service Applications page, click the Search service application.
On the Search Administration page, in the Quick Launch, in the Diagnostics section, click Crawl Health Reports.
On the Search Service Application: Crawl Reports page, click the crawl health report that you want to view.

The following table shows which reports are available.

Crawl log:

The crawl log tracks information about the status of crawled content. This log lets you determine whether crawled content was successfully added to the index, whether it was excluded because of a crawl rule, or whether indexing failed because of an error. The crawl log also contains information such as the time of the last successful crawl and whether any crawl rules were applied. You can use the crawl log to diagnose problems with the search experience.

To view the crawl log

Verify that the user account that is performing this procedure is an administrator of the Search service application, or has Read permissions to it.
In Central Administration, under Application Management, click Manage service applications.
On the Service Applications page, click the Search service application.

To view usage reports

Verify that the user account that is performing this procedure is an administrator of or has Read permissions to the Search service application.
In Central Administration, under Application Management, click Manage service applications.
On the Service Applications page, click the Search service application.
On the Search Administration page, in the Quick Launch, in the Diagnostics section, click Usage Reports.
On the View Usage Reports page, click the usage or search reports view that you want view.

Configure diagnostic logging SharePoint 2016

Posted on 15/01/2017 by Deviprasad Panda

The SharePoint Server 2016 environment might require configuration of the diagnostic logging settings after initial deployment, after upgrade, and if a change is made to the environment, such as adding or removing a server. Below description all about Configure diagnostic logging SharePoint 2016

The guidelines in the following list can help you form best practices for the specific environment.

* Change the drive to which the server writes logs:

By default, SharePoint Server 2016 writes diagnostic logs to the same drive and partition on which it was installed. Because diagnostic logging can use a large amount of drive space and compromise drive performance, you should configure SharePoint Server 2016 to write to another drive on which SharePoint Server 2016 is not installed.

You should also consider the connection speed to the drive on which SharePoint Server 2016 writes the logs. If verbose-level logging is configured, the server records a large amount of data. Therefore, a slow connection might result in poor log performance.

* Restrict log disk space usage:

By default, the amount of disk space that diagnostic logging can use is unlimited. Therefore, restrict the disk space that logging uses, especially if you configure logging to write verbose-level events. When the disk reaches the restriction, SharePoint Server 2016 removes the oldest logs before it records new logging data.

* Use the Verbose setting sparingly:

You can configure diagnostic logging to record verbose-level events. This means that SharePoint Server 2016 records every action that it takes. Verbose-level logging can quickly use drive space and affect drive and server performance. You can use verbose-level logging to record more detail when you are making critical changes and then reconfigure logging to record only higher-level events after you make the change.

* Regularly back up logs:

Diagnostic logs contain important data. Therefore, back up the logs regularly to ensure that this data is preserved. When you restrict log drive space usage, or if you keep logs for only a few days, SharePoint Server 2016 automatically deletes log files, starting with the oldest files first, when the threshold is met.

* Enable event log flooding protection:

When you enable this setting, SharePoint Server 2016 detects repeating events in the Windows event log, and suppresses them until conditions return to a typical state.

You can set the level of diagnostic logging for the event log and for the trace log. This limits the types and amount of information that are written to each log.

The following tables define the levels of logging that are available for the event log and trace log.

Configure diagnostic logging by using Central Administration :

In Central Administration, on the home page, click Monitoring.
On the Monitoring page, in the Reporting section, click Configure diagnostic logging.
On the Diagnostic Logging page, in the Event Throttling section, configure event throttling as follows:To configure event throttling for all categories:
1. Select the All Categories check box.
2. Select the event log level from the Least critical event to report to the event log list.
3. Select the trace log level from the Least critical event to report to the trace log list.
To configure event throttling for one or more categories:
1. Select the check boxes of the categories that you want.
2. Select the event log level from the Least critical event to report to the event log list.
3. Select the trace log level from the Least critical event to report to the trace log list.
To configure event throttling for one or more subcategories (you can expand one or more categories and select any subcategory):
1. Click the plus (+) next to the category to expand the category.
2. Select the check box of the subcategory.
3. Select the event log level from the Least critical event to report to the event log list.
4. Select the trace log level from the Least critical event to report to the trace log list.
To return event throttling for all categories to default settings:
1. Select the All Categories check box.
2. Select Reset to default from the Least critical event to report to the event log list.
3. Select Reset to default from the Least critical event to report to the trace log list.
In the Event Log Flood Protection section, select the Enable Event Log Flood Protection check box.
In the Trace Log section, in the Path box, type the path of the folder to which you want logs to be written.
In the Number of days to store log files box, type the number of days (1-366) that you want logs to be kept. After this time, logs will automatically be deleted.
To restrict the disk space that logs can use, select the Restrict Trace Log disk space usage check box, and then type the number gigabytes (GB) you want to restrict log files to. When logs reach this value, older logs will automatically be deleted.
After you have made the changes that you want on the Diagnostic Logging page, click OK.

Configure diagnostic logging by using Windows PowerShell :

Verify that you have the following memberships:

securityadmin fixed server role on the SQL Server instance.
db_owner fixed database role on all databases that are to be updated.
Administrators group on the server on which you are running the Windows PowerShell cmdlets.

An administrator can use the Add-SPShellAdmin cmdlet to grant permissions to use SharePoint Server 2016 cmdlets.

2. On the Start menu, click All Programs.
3. Click SharePoint 2016.
4. Click SharePoint 2016 Management Shell.
5. To change the drive to which the server writes logs, at the Windows PowerShell command prompt, type the following command:

Set-SPDiagnosticConfig -LogLocation D:\DiagnosticLogs

6. To restrict log disk space usage, at the Windows PowerShell command prompt, type the following command:

Set-SPDiagnosticConfig -LogMaxDiskSpaceUsageEnabled

Or assign the maximum disk space for logs:

Set-SPDiagnosticConfig -LogDiskSpaceUsageGB 500

7. To view the current logging level, at the Windows PowerShell command prompt, type the following command:

Get-SPLogLevel

8. To change the logging level, at the Windows PowerShell command prompt, type the following command:

Set-SPLogLevel -TraceSeverity Monitorable

To set all categories back to default levels, at the Windows PowerShell command prompt, type the following command, and then press ENTER:

Clear-SPLogLevel

9. To enable event log flooding protection, at the Windows PowerShell command prompt, type the following command:

Set-SPDiagnosticConfig -EventLogFloodProtectionEnabled
