In this post, we’ll show you how to monitor the status of your MongoDB servers using Studio 3T’s Server Status Charts feature. Try it today.
Introduction
Studio 3T’s Server Status Charts show real-time updates of what’s happening on a MongoDB instance.
This makes it easier to monitor particular things of interest on production, development, test, or local instances.
Open Server Status Charts
You can open a Server Status Charts tab by right-clicking on a connection (or database, or collection) and selecting Server Status Charts from the Server Info menu:
Choose your charts
You can customize which charts are shown by clicking on Select Charts in the upper right hand side corner of the Server Status Charts tab:
For example, if we wanted to focus on Operation Counts, Current Connections, and Current Network Traffic, we would select only those, and the charts will be laid out intelligently to accommodate them:
What the chart information means
In this section, we’ll explain the information shown on each chart.
Note that the information displayed in the charts may be:
Charts show information since the start of a particular point until the present moment, e.g. all events of a particular type since the database started
Charts show information about a particular event that occurred during an update period, e.g. if we have the ‘Update frequency’ set to ‘2 sec’, then the chart will show all events of that particular type that occurred within 2 second periods
Charts show information about a particular event as it was at the point in time that the MongoDB server status was requested from the database
– where the charts show information since the start of a particular point until the present moment, e.g. all events of a particular type since the database started.
The table below details each of the MongoDB server status charts:
| Operation Counts Per Update Period The number of database operations by type during the update period. |
| Active Clients Point in Time The number of the active client connections performing read and write operations. |
| Current Queue Point in Time The number of operations that are currently queued and waiting for the read or write lock. |
| Current Connections Point in Time / Per Update Period The number of incoming connections from clients to the database server. ‘In use’ and ‘Available’ report the point in time values, ‘Total created’ shows values per update period. |
| Current Network Requests Per Update Period The number of distinct requests that the server has received during the update period. |
| Current Network Traffic Per Update Period The number of bytes that reflects the amount of network traffic received by and sent from this database during the update period. |
| Total Connections Created Cumulative Count of all incoming connections created to the server. This number includes connections that have since closed. |
| Total Network Requests Cumulative The total number of distinct requests that the server has received. |
| Total Network Traffic Cumulative The total number of bytes that reflects the amount of network traffic received by and sent from this database. |
More detailed information about the counters the chart data are based upon can be found in the MongoDB documentation.
