What does 'Confidence Level' mean in VERITAS Cluster Server (VCS) ?

Solution



The VCS Agent Developer's Guide states:

The confidence level is informative only; it is not used by VCS. It is returned only when the resource status is online.

A C++ entry point can return a confidence level of 0-100. A script entry point combines the status and the confidence level in a single number.

For example:

100 indicates offline.
101 indicates online and confidence level 10.
102 indicates online and confidence level 20.
103-109 indicates online and confidence levels 30-90.
110 indicates online and confidence level 100.

What is 'Confidence Level' ?

This feature was originally implemented into the Agent Application Program Interface (API) as a supplementary return value from monitor entry points. C++ monitor entry points return a VCSAgResState primitive, either VCSAgResOnline or VCSAgResOffline and conf_level. For script based Agents, the confidence level and state were merged into the "exit" value of the script giving the single numbers defined above.
