You can use three major performance metrics to monitor instance performance in the Lindorm Time Series Database (TSDB) console. The three performance metrics are the number of data points that are written per second, the number of time series, and the disk usage.


Note The steps for monitoring instance performance based on the three metrics are the same. In this topic, an example is provided to describe how to monitor instance performance based on the number of data points that are written per second.
  1. On the Instances page in the TSDB console, find the instance that you want to monitor and click Monitor in the Actions column.
  2. In upper-right corner of the Instance Monitoring page, select the time range during which you want to view the monitoring statistics.
    • You can select 1 Hour, 6 Hours, 1 Day, 7 Days, or 14 Days from the drop-down list of Recent to specify a time range to query.
    • TSDB automatically performs health checks for read and write operations on instances. In this case, a test data point is written to an instance every 10 seconds. Even if you do not write data points to an instance, the system writes an average value of 0.1 data point to the instance per second.
    Note The query result is displayed in a coordinate graph, as shown in the preceding figure. The x-axis is the time, and the y-axis is the metric. To view the metric value at a specific point in time, move the cursor to the point in time in the graph.
