Tasks by Frequency of Performance
This chapter divides the day-to-day operations and monitoring tasks into categories based on frequency of performance.
The tasks are grouped by the following frequencies:
Constantly
Tasks in this category either require constant monitoring or should be performed more than once every five minutes.
The following table describes the tasks that are in this category:
| Task | Notes |
|---|---|
| Check ping | |
| Check SSH | |
| Monitor CPU utilization | Alert on high CPU utilization. |
| Monitor for errors using Health Monitor and Log Monitor | |
| Monitor for memory swapping | |
| Monitor for mirror differences | Each time you make manual changes on a mirror member, you should decide if you need to make the same changes on the other mirror members. |
| Monitor for network packet dGOPS or retransmissions | Alert when excessive rates of network packet dGOPS or retransmissions occur. |
| Monitor InterSystems IRIS queues | Alert when memory swapping occurs. |
| Monitor memory utilization | Alert on high memory utilization. |
| Review Web Gateway error log | Alert on errors. |
| Review web server error logs | Alert on errors. |
Hourly
Tasks in this category should be performed hourly.
