> - to grep a pattern by t1 use:
> zkgrep --zkCfg zkCfg --by t1 --pattern patterns...
>
> - to grep a pattern between t1 and t2 use:
> zkgrep --zkCfg zkCfg --between t1 t2 --pattern patterns...
>
> for example, to find fail-over latency between t1 and t2, use:
> 1) zkgrep --zkCfg zkCfg --between t1 t2 --pattern "closeSession" | grep
> {fail-node session-id}
> 2) zkgrep --zkCfg zkCfg --between t1 t2 --pattern "/{cluster}" | grep
> "CURRENTSTATES" | grep "setData" | tail -1
>
> fail-over latency = timestamp difference between 1) and 2)
