Guidelines for monitoring with the CandleMonitor node
See the following guidelines for monitoring with the CandleMonitor node:
- For production flow statistics, place the CandleMonitor node immediately after MQInput (or other input) nodes and set the type attribute to input.
- For output rates and counts, place the CandleMonitor node immediately in front of MQOutput, MQReply, and Publication nodes and set the type attribute to output.
- For any other placement in the flow, do not set the type attribute to input or output, because inaccurate data might be generated.
- Generally, an eventMessage attribute must
be specified only for nodes with a type attribute of subFlowInput, subFlowOutput,
and other. Do not set this attribute for the typical
processing part of a flow or for a node with a type attribute of input
or output (unless the node is not used frequently and there is a specific
reason for doing so) because it might have an adverse effect on system
performance.
- For message flow development, nodes that have the type of other can be used to determine areas of a flow that have poor performance.
- If you are going to shut down the broker or agent, the broker or agent must complete the entire shutdown process whenever possible.
