[jira] [Created] (ZOOKEEPER-3770) Monitoring script support for 3.6

Michał Lisowski created ZOOKEEPER-3770:
------------------------------------------

             Summary: Monitoring script support for 3.6
                 Key: ZOOKEEPER-3770
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3770
             Project: ZooKeeper
          Issue Type: Improvement
          Components: contrib
    Affects Versions: 3.6.0, 3.6.1, 3.6.2
         Environment: OS: Red Hat Enterprise Linux Server release 7.7

Zookeeper version: 3.6.0

Python version: 2.7.5
            Reporter: Michał Lisowski
             Fix For: 3.6.0, 3.6.1, 3.6.2


The zookeeper-contrib-monitoring script needs fixes to support zookeeper 3.6.

Found issues:
 * 4lw.commands.whitelist=mntr,ruok,stat is now required for the script to work, as 4 letter words commands are now all disabled by default (README has to be updated).
 * zk_avg_latency metric is now float, the script has them all as strings anyway, and now it fails when trying to compare for example the '0.0' string to the warning and critical values.
 * Now, since 'mntr' command returns much more data (even more with the Prometheus Metrics Exporter), python socket communication has to be changed to support much more data and data chunking.
