zabbix_sender always fails

[joewac]

I am trying to fake out the value of a specific key from a host so that I can test remote commands. Here is the trigger as entered into Zabbix, which works just fine.

{syrlgf4n6g:vfs.fs.size[/working,pfree].avg(1m,0)}<80

In order to test my remote command Action, I am trying to use zabbix_sender with the following command:

zabbix_sender -z syrlgf4n6h -s syrlgf4n6g -k "vfs.fs.size[/working,pfree]" -o 15.0 -vv

But I always get this:

zabbix_sender [26378]: DEBUG: answer [{"response":"success","info":"processed: 0; failed: 1; total: 1; seconds spent: 0.000038"}]
info from server: "processed: 0; failed: 1; total: 1; seconds spent: 0.000038"
sent: 1; skipped: 0; total: 1

Is there something wrong with my zabbix_sender command syntax?

Thanks

Make sure your -s parameter matches the host (not display name) in Zabbix.

If your host is monitored via a proxy, -z should be your proxy name (as configured in Administration -> Proxies).

Make sure you are sending a valid value type (float, integer e.t.c) for the item.

I checked all the parameters. Per zabbix, the host name is the same as what I am putting in the -s parameter. I am not using a proxy, and the particular value for the key should be a float, so I entered 15.0. If I enter 15, I get the same result.

I'm pretty sure the server is getting the data, but for some reason does not like it. Is there a log on the server some place that has more information? I checked all the logs on the server in /var/log/zabbix, but did not find any indication of any error due to the zabbix_send.
