Data Persistence
IO metric data is collected at defined intervals, based on the probe or integration and the configured interval. The length of time metric data is kept in the IO portal depends on its granularity. For example, 1 to 10 second data is kept for 8 days, after which it is aggregated. This is important to understand in reporting. Report ranges that include a long period will show the most granular data (1 sec, 10 sec) for only the period of time shown here.
The table below shows the retention policy for the different summary levels.
Summary Level | Days of Retention |
|---|---|
1 second | 8 days |
10 seconds | 8 days |
1 minute | 16 days |
5 minutes | 35 days |
10 minutes | 65 days |
1 hour | 184 days |
4 hours | 400 days |
1 day | 3660 days |
Data Persistence Example
This chart shows Avg Read Latency metric data for the last 30 days (daily averaged value). We can drill down to view more granular data, but only in the context of granularity and the defined data persistence.
We can view 1 minute data for the last 16 days.
But only 5 minute data for the 19 days before that.
