The Statistics page displays a collection of data that you can use to monitor the performance of your YouTrack InCloud instance. When users report that YouTrack is slow, use these metrics to help diagnose the problem.
The YouTrack InCloud support team monitors the servers that support our hosted instances around the clock. We use a range of monitoring tools to identify events that can negatively impact performance and resolve them as quickly as possible.
That said, there are several factors that affect the responsiveness of your instance. When users complain that the instance is slow, use the metrics on this page to determine whether your instance is simply overloaded temporarily or requires the attention of the support team.
The total amount of running time since the last YouTrack service start.
The date and time of the last YouTrack service start.
Database Background Threads
The number of dedicated threads that populate the database queries cache.
Our servers normally require only one or two threads to perform these tasks. The support team monitors these threads to ensure that your server has enough resources to process its work.
Pending Async Jobs
The number of tasks that are waiting to be executed, usually background tasks that populate the database queries cache.On a hosted instance server, you should see that this queue of tasks is processed fairly quickly.
Cached Results Count in Database Queries Cache
The number of records that are held in the cache for search query results. Cached results improve the performance of search queries against the database.
Database Queries Cache Hit Rate
The percentage of search queries that are satisfied by results that are stored in the cache.
BLOB Strings Cache Hit Rate
The percentage of text-based data that is served from the BLOB strings cache. This rate does not affect performance as significantly as the Database Queries Cache Hit Rate does, but can affect page load time.
The number of database transactions that have been processed since the last service start time.
Transactions per Second
The average number of database transactions that are processed each second. Measures the immediate server load.
Requests per Second
The average number of requests that are processed each second.
Database Size without BLOBs
The total size of your database, excluding binary large objects (BLOBs).
Full Database Size
The total amount of space on the server that is currently occupied by your YouTrack database. Use this metric to determine whether you need to reduce the size of your database or upgrade your subscription plan to increase your storage limit.
Text Index Size
The amount of space in the database that is used by the text index. The text index is used to find matching words and phrases in search queries.
|The number of users who are currently using the application.|
If there numbers are relatively large, it indicates that the traffic in your instance is very heavy. You may experience poor performance not because of any problem with the application itself, but because there is a large number of incoming requests that are generated by a large number of users. The following metrics are shown:
Report Calculation Threads
The number of threads that can be used to calculate reports. Basically, shows the number reports that can be calculated simultaneously.
Notification Analyzer Threads
Shows a number of threads that are allocated for processing events (updates in issues, saved searches, tags, and so on) and analysing the required notifications. The more threads allocated, the quicker the events queue is processed and calculated, and the quicker the notifications are sent.
Notification Analyzer Queue Size
The number of issue updates that are waiting to be processed by the notification analyzer.
Notification Sender Queue Size
The number of notification messages that have been analyzed and processed and are waiting to be transferred to the mail server for sendout.
User Action Job Processor Queue Size
The number of user-initiated transactions that are waiting for execution.
Hub Events Queue Size
The number of events that have been processed in the Hub service that are waiting to be synchronized with the YouTrack database.
