[Zabbix-users] Problem with LLD: lots of became supported / became not supported

[Tiago C. <tia...@gm...>]

Hello guys,


I'm using zabbix 2.4.7 and Low Level Discovery who parses the output of
`varnishadm  backend.list` command and send to zabbix, ex:

```
[root@host4 ~]# varnishadm  backend.list | column -t | grep apetit -C 2
be_bucket(127.0.0.1,,2676)                       1     probe  Healthy  (no
   probe)
be_apetitar(127.0.0.1,,2677)                     3     probe  Healthy  (no
   probe)
be_adeliveria(127.0.0.1,,2675)                   1     probe  Healthy  (no
   probe)
```

Everything is working good (the itens are plotting, the graph is working
and also the trigger), except for one detail:

On the host, I can see lots of "active check
"varnish.backends[be_xxxx,conn]" is not supported".
And in the server logs, I can see lots of, for example:

```
  7603:20160304:163453.953 item "host4:varnish.backends[be_apetitar,conn]"
became supported
  7603:20160304:163544.366 item "host4:varnish.backends[be_apetitar,conn]"
became not supported: Unsupported item key.
  7598:20160304:163654.251 item "host4:varnish.backends[be_apetitar,conn]"
became supported
  7603:20160304:163738.887 item "host4:varnish.backends[be_apetitar,conn]"
became not supported: Unsupported item key.
  7600:20160304:163854.747 item "host4:varnish.backends[be_apetitar,conn]"
became supported
  7610:20160304:163942.025 item "host4:varnish.backends[be_apetitar,conn]"
became not supported: Unsupported item key.
```

Even using debug level, I can't understand how to find the root cause of
this flapping. Do you have any idea?

Thanks!
