Search Admin Platform Services: Repository Initialization Failed
Alert Name: Search Admin Platform Services: Repository Initialization Failed
Summary: The PackageManager service in each component will read the Default-manifest.txt on component startup to find the current status of the repository quickly. While running, the PackageManager in each component obtains updates about installs and uninstalls from the host controller. In this case, the repository could not be initialized. This means that there was a failure when the repository was initializing on host controller startup. For example, during a primary failover or during a repository reset.
Cause
The cause could be an ACL issue or a corrupted repository manifest file. If it is a corrupted repository with a good manifest file, initialization will try to rebuild the repository again. However, the same event is also sent when rebuild fails.
Resolution
Check for potential ACL issues.
Follow this procedure for fixing the repository on secondary (not primary) hosts:
Stop the host controller.
Delete the directory C:\Program Files\Microsoft Office Servers\15.0\Data\Office Server\Applications\Search\Repository.
Start the host controller. This will affect the host controller to create an empty repository with a GUID that does not match the primary. So, the secondary will immediately start to replicate the contents of the primary.
Search Admin Platform Services: Repository Installation Failed
Alert Name: Search Admin Platform Services: Repository Installation Failed
Summary: Repository installation fails for the file indicated. When dictionary installation fails for the primary, users should be aware that linguistic features such as query suggestions might get outdated.
Cause
The file may already be installed in the repository, or the related timer job may have failed.
Resolution
Check the repository. Make sure that a dictionary compilation timer job has completed successfully after the event. You can manually trigger the timer job from Central Administration or by using Microsoft PowerShell in order to re-install.
Search Admin Platform Services: Repository Replication
Alert Name: Search Admin Platform Services: Repository Replication
Summary: This situation occurs in secondary repositories. The repository in the local host controller has found that it has a lower repository version than the primary host controller (or lower version than other secondary host controllers if the primary is down). When this happens, the local repository attempts to obtain the latest version from the primary or a secondary based on how it is triggered. This indicates that something went wrong during the replication.
Cause
Connection to the remote repository which is being replicated can be lost due to a network issue or due to a remote repository (host controller) issue during replication. The local repository can be corrupted or have an ACL issue.
Resolution
If persistent, a manual intervention might require to make it correct based on the problem (see cause). Except for the obvious resolutions on network and ACL and so on, remote host controller can be restarted. If the repository is corrupted, usually it is automatically rebuilt.
Search Analytics: analysis run state Search Analytics
Alert Name: Search Analytics: analysis run state Search Analytics
Summary: An analysis can encounter different problems. Hence the system cannot guarantee a successful run of search analytics analysis. The timer job, following the analysis failure model, will try to re-schedule a new analysis run to prevent from waiting until daily schedule is triggered.
Symptoms: Monitor is triggered when unsuccessful analysis run is detected by the timer job.
Cause
One or more of the following might be the cause:
Analytics processing component(s) or some other farm components are not available.
Databases (Link database, analytics reporting database, etc.) are not running or reachable.

Search Analytics: Timer job cannot resolve Link database
Alert Name: Search Analytics: Timer job cannot resolve Link database
Summary: The timer job will check that all Link database partitions are available before it tries to start the search analytics analysis. Symptoms: If the Link database partitions are unavailable when it is time to start a new analysis run, the start try will be aborted. New Link database checks followed by a new start try will be performed in the next timer job polls (every 10 minutes).
Cause
One or more of the following might be the cause:
Unable to resolve the Search service application.
Link database connection timed out.
Link database connection is refused.
Link database is not available.
Resolution
Verify that the Link database is available and reachable. Also verify that the user has access to read from the Link database.
Search Analytics: analysis run state search analytics
Alert Name: Search Analytics: analysis run state search analytics
Summary: The search analytics analysis is started by its timer job. The analysis will run until all its tasks are completed, and the analysis state will be set to Stopped. If some tasks cannot be completed, the analysis run will be stopped (after some retries) and the state set to Failed. Stopped before completion indicates that the analysis has reached the Stopped state, but all analysis tasks have NOT completed. Some of the work done by the analysis might have been sent to the index then, but to make sure nothing is lost and all of the work is processed again during next analysis run.
Cause
Analysis is stopped for the following reasons:
A manual stop on a running search analytics analysis was performed
Or, system maintenance tasks require stopping a running search analytics analysis.
Resolution
Check the state of the search analytics analysis and any active system maintenance tasks.
Search Gatherer: Disk Full Crawler
Alert Name: Search Gatherer: Disk Full Crawler
Summary: As the crawler crawls content, it creates files in a temporary location. This temporary location can grow over time. The disk where the temporary location is located is running out of space. SharePoint experiences the following symptoms when this happens:
The crawl does not progress and seems to stall.
The crawl logs show no new crawled documents.
Cause
The disk on which the crawler creates temporary files is running out of space.
Resolution
Free up space on the disk on which the crawler creates the temporary files. To free up disk space: Use Disk Cleanup to delete temporary files on the drive where the temporary index files are stored. Use the procedure following this one to determine the location of the index files.
Note
If the temporary files are located on a drive other than the operating system drive (drive C), you must restart the search service to test the performance of the crawler after you delete the temporary files.
After Disk Cleanup is complete, test the performance of the crawler.
If the crawler is not crawling content, delete unnecessary files and folders on the selected drive.
If you cannot clear any disk space, restart the search service. Restarting the search service recreates the Temp directory for crawled files. In a Command Prompt window, run the command
net stop osearch15to stop the search service. Run the commandnet start osearch15to restart the search service.
Search Usage Analytics: Analysis configuration failed
Alert Name: Search Usage Analytics: Analysis configuration failed
Summary:

Search Usage Analytics: Reporting API write failure
Alert Name: Search Usage Analytics: Reporting API write failure
Summary: Background or symptoms:
The information written to the reporting API or database is used if the cache files must be rebuilt. When usage analytics cannot write to the reporting API, this means that the recommendations and data aren't updated. Counts presented to the user are therefore out of date, and old or wrong data will also be presented next time that the cache is rebuilt.
The Reporting API could not be read so that no cache files could be created and the analysis will therefore not be run. Running the analysis in this state would in effect overwrite the current data.
Impact:
There will be no usage analytics analysis run.
Recommendations will not be updated for items in the system.
Cause
One or more of the following might be the cause:
Reporting API is returning an error saying database is down.
Reporting API is responding that the wrong data is being sent (nothing is stored).
The reporting API cannot be reached (networking issues).
Reporting API is returning an error saying database is down
Reporting API is returning empty (wrong data).
The cache dumper is malfunctioning.
Resolution
Verify that there are no database problems in the system, and make sure that the analytics reporting database is functioning.
Verify that analytics processing component is functioning. This means that analyses can run.
Check for any networking issues.
Search Usage Analytics: Store not available
Alert Name: Search Usage Analytics: Store not available
Summary: Background or symptoms:
Usage analytics cannot communicate with the event store. The usage analysis will not be started, and usage analytics data in the analytics reporting database and the search index will be stale.
During the first step of the usage, the system fetches the event data from the event store. This is the raw input to the analysis. It contains the actions for the users in the system. Without this data, the analysis cannot be run.
Cause
One or more of the following might be the cause:
Network outage, Event Store process is down, or the event store is returning errors in response to request.
The event store can be down. The event store is returning no data because the components registering events are not functioning correctly, or there are networking issues so that the event store cannot be reached.
