Inconsistent data between samples of the PostgreSQL agent
说明
PostgreSQL agent data seems to be inconsistent between collections
原因
Properties which should not change are alternating between different values and metrics which would normally be steady are ping ponging between two different values.
解决办法
It is likely that the agent has been configured to connect to the PostgreSQL server through a proxy used for load balancing or high availability between multiple PostgreSQL servers. As a result, the agent is performing data collections on multiple servers and combining them. The agent should be reconfigured to connect to the PostgreSQL server directly and more agents added to monitor the other servers if desired.
