Hi Shiva,
As per my understanding, we can modify the collection policy to make changes in to stats. For that purpose, lets say I want to update both collection interval and reporting interval to 30 secs then i have to post the below XML Request
1<configConfMos cookie=""
2inHierarchical="false">
3 <inConfigs>
4 <pair key="stats/coll-policy-port">
5 <statsCollectionPolicy collectionInterval="30seconds"
6 dn="stats/coll-policy-port" reportingInterval="30minutes"
7 status="modified"></statsCollectionPolicy>
8 </pair>
9 </inConfigs>
10</configConfMos>
Let me know, if this works for you.
