Symptoms
How long does ViPR SRM keep raw data and when does it aggregate?
Cause
Resolution
File configured in
/opt/APG/Backends/APG-Backend/Default/conf/config.xml
Default values are as follows:
<raw-data span-time="31d" />
<aggregate name="1hour" span-time="61d" />
<aggregate name="1day" span-time="365d" />
<!-- <aggregate name="1dayAligned" xsi:type="AlignedAggregate" span-time="365d" /> -->
<!-- 7 years of 365 days ~= 2555 days -->
<aggregate name="1week" span-time="2555d" />
Which means by Default,
SRM keeps the 5 minute raw incremental data for 31 days, after 31 days, it will aggregate the raw data to 1 hour incremental data and be kept for 61 days.
After 61 days, SRM will aggregate the 1 hour data to 1 day incremental and keep this for 365 days and after a year, only 1 week incremental for 7 years.
It is not recommended to change these values as it can affect the database size and amount of metrics kept.
