We are observing that the Agent View is taking 17 to 20 sec to load.
Release : SAAS
Component : APM SAAS ENTERPRISE
ATC calls TAS to get all agents matching the universe/filter.
· Then the ATC calls the card service to get all metric data for the agents, e.g. CPUs, Memory, metric count etc.
Thus, the card service spike is probably related to this. If you query plenty of data, this means many agents and large time range, it needs to aggregate all these. So, the first time when the agent view loads, it takes time as Time aggregation are usually cached so probably a second call (page refresh) might be faster because many of these aggregation and computation remains in the cache.
SAAS Fixes implemented. Down to 7-8 seconds. This is expected due to number of agents queried about.
