Poll strategy for server monitors

How does poll strategy setting work?

When configuring thresholds for performance metrics, you can set strategies depending on which the monitoring agent will send alerts during a threshold breach. Here are the available options:
  1. Poll count
  2. Poll average
  3. Time duration
  4. Average time
  5. Poll sum
  6. Time sum
  7. Min poll
  8. Min time
  9. Max poll
  10. Max time
  11. 95th percentile poll
  12. 95th percentile time
The default strategy option is Poll count.

Poll Count:
Consider the threshold for CPU utilization is configured as follows:

Only when the CPU usage for 5 polls continuously exceeds 70%, Site24x7 will send a Trouble alert to the user.

Poll Average:
Consider the threshold for CPU utilization is configured as follows
Only when the average of the CPU usage for 5 polls continuously exceeds 70%, Site24x7 will send a Trouble alert to the user.

Time Duration:
Consider the threshold for CPU utilization is configured as follows:
Only when the CPU usage exceeds 70% in a 5-minute duration, Site24x7 will send a Trouble alert to the user.

Average Time:
Consider the threshold for CPU utilization is configured as follows:

Only when the average of the CPU usage exceeds 70% in a 5-minute duration, Site24x7 will send a Trouble alert to the user.  

Poll sum:
Consider the threshold for Failed Requests is configured as follows:
Only when the sum of 5 continuous polls exceeds 10 failed requests will Site24x7 send a Trouble alert to the user.

Time sum:
Consider the threshold for Failed Requests is configured as follows:
Only when the number of failed requests exceeds 10 within a 5-minute interval will Site24x7 send a Trouble alert to the user.

Min poll:
Consider the threshold for Page Views is configured as follows:
Only when the minimum poll value of page views for 10 continuous polls is lesser than 5 will Site24x7 send a Trouble alert to the user.

Min time:
Consider the threshold for Page Views is configured as follows:
Only when the minimum poll value of page views in a 10-minute duration is lesser than 5 will Site24x7 send a Trouble alert to the user.

Max poll:
Consider the threshold for Exceptions is configured as follows:
Only when the maximum poll value of exceptions for 10 continuous polls exceeds 100 will Site24x7 send a Trouble alert to the user.

Max time:
Consider the threshold for Exceptions is configured as follows:
Only when the maximum poll value of exceptions within a 10-minute intervel exceeds 100 will Site24x7 send a Trouble alert to the user.

95th percentile poll:
Consider the threshold for Execution Times is configured as follows:
Only when the 95th percentile value of execution times for 5 continuous polls is 10ns will Site24x7 send a Trouble alert to the user.

95th percentile time:
Consider the threshold for Execution Times is configured as follows:
Only when the 95th percentile value of execution times in a 5-minute interval is 10ns will Site24x7 send a Trouble alert to the user.
