Measuring a TrueSight Presentation Server's slow response time
Relevant attribute
- ====
Response-time-when-invoke-TSPS-ResponseTime
This attribute reports the response time between the TrueSight Presentation Server and the registered TrueSight components.
This attribute uses the following metric values:
Response time range | Description |
---|---|
0-10000 | The TrueSight Presentation Server is responsive in processing requests. |
10001-Above | The TrueSight Presentation Server’s response time is slow. |
The following issues could cause the attribute's metric to be in a RED\CRITICAL or ALARM state:
- Network latency
- Host or operating system resources outage
- Heavy network traffic
- An Application or component error
- Child processes consuming or utilizing large amounts of memory or CPU capacity
Suggested actions for slow response time
- ====
If the attribute's metric indicates a slow response time:
- Verify the network latency by trying to connect to the TSPS host in a new browser window.
- Check the network performance by using one of the following methods:
- Ping the host to check the time-to-live value between the TSPS host and the network.
- Use a native utility to measure the latency from the TSPS host to the network
For example, your system administrator can use the following cURL or Wget utility:curl -s -w %{time_total}\\n -o /dev/null https://<TrueSight Presentation Server FQDN>/#/time wget -pq --no-cache --delete-after https://<TrueSight Presentation Server FQDN>
- Determine if there is enough disk space available on the system where the Presentation Server is installed.
- Confirm that there is enough CPU capacity and memory available for the Presentation Server to operate efficiently.
