item for checking zabbix connection

[kopspa]

hi,
how i can make an item that
report the seconds from the last connection from zabbix_agentd to zabbix_server (active check)

and then a trigger if seconds > 120

many thanks!

Can you explain a bit more what you are trying to do?

[kopspa]

i want to check if a remote zabbix_agentd is connected to my zabbix_server

i use only active checks (because all my monitored machines are behind a firewall/nat) so i can't connect to the monitored zabbix_agentd port!

i hope that you understand it now :)

Perhaps you can do this with item "agent.ping" ...
(see http://www.zabbix.com/manual/v1.1/config_items.php for more information)

[kopspa]

can't be pinged... we have very strict policies for the firewalls

i need to determine if a remote zabbix_agentd is connected to my zabbix_server (via a tcp check or any other trick)

[erisan500]

Why don't you just use "status" and alert when status changed to 1?

[kopspa]

doesn't return anything (tried as simple check, zabbix agent and zabbix agent active)
it shows

Status | - | - | - | Graph (in Overview -> Latest Data)

i think that it must return 0 or 1, no?

[erisan500]

What version are you using?

Status used to work in beta9 but seems to be broken in beta10 :/

[kopspa]

server side beta9
client side beta9 and 10
but returns nothing on all hosts (b9 and b10)

[kopspa]

otherwise can i make a check like this?

if zabbix_server doesn't receive data from a zabbix_agentd for 5 minutes (or if the time of the last check is more then 5 minutes), than launch the trigger (and then the action)

anyone can help me??? my setup is almost complete (basic checks, as if process slapd,mysqld, ecc are running ecc), but i don't know how to make the item and the trigger for this condition (i can't find something useful in the docs)!

Function nodata(<sec>) will return 1 of no data were received for an item.

[kopspa]

ok but i see in the documentation that is only supported in 'zabbix trapper' items

what is a zabbix trapper? i can't find anything in the docs.
if i try to make a trapper item, i can't set the 'update interval'

[erisan500]

You need to use that in a trigger like:

{Host.Win32:vfs.fs.size[c:,free].nodata(120)}=1

[Alexei]

ok but i see in the documentation that is only supported in 'zabbix trapper' items

The documentation is wrong, sorry for this. It is supported for any item regardless of its type.

[kopspa]

now my setup is ok (and the boss is happy! :D )

thanks very much

And another happy user, glad you solved your problems ;)
