Ambari Metrics Monitor won't start

Explorer

I'm trying to run Amrabi metrics monitor on one host from Ambari Web, but get the following error:

Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/common-services/AMBARI_METRICS/0.1.0/package/scripts/metrics_monitor.py", line 58, in <module>
    AmsMonitor().execute()

    kinit_path_local = functions.get_kinit_path(default('/configurations/kerberos-env/executable_search_paths', None))
NameError: name 'functions' is not defined

I've alreadн tried to reinstall ambari-agent, but that didn't help. I've started the monitor manually at this host and I can see the metrics in Ambari Web, but Ambari UI still shows that the monitor doesn't work

can you check whether the agent is the same version as ambari server? Can you try to restart the agent on that machine and try again?

Yes, I've checked that ambari-server and ambari-agent are the same version. I've restarted the agent but it didn't help, result is the same.

@Kirill Elsukov

Is the environment kerberised? Also what's the Ambari version you are using?

Is this an upgrade environment? Was AMS upgraded as well - refer to Upgrading AMS
