snmp ping problem.. !!!

[pfft]

hello,
i got one problem with my cacti setup :

i have 2 script commands that searches through a file for data with input from hostname field of the Device thingie.

the problem is i get errors from snmp stuff coz it is using the hostname to check the host.
and the hostname is in the Client23 format not numeric ip or fqdn hostname..

so i get these in cactid.log :

12/06/2004 01:08:05 PM - PHPSVR: Poller[0] PHP Script Server has Started - Parent is cactid
12/06/2004 01:08:05 PM - CACTID: Poller[0] ERROR: Problem initializing SNMP session 'Client23'
12/06/2004 01:08:05 PM - CACTID: Poller[0] WARNING: Unknown host Client23
12/06/2004 01:08:05 PM - PHPSVR: Poller[0] ERROR: Input Expected, Script Server Terminating

so how do i disable this host availability check so i can use my two scripts and another two ping loss and rtt scripts in the same time?
because if i put in the hostname the ip of the Client23 everything workd fine except the first two script command stuff that requires "Client23" instead of the numeric ip or hostname.

for a workaround how can i use the Description fields to feed the script commands ?
in Data Input Methods cani use instead of "hostname" at Special Type Code something like "description" to get the Description instead of Hostname of a Device?

thx.

Define a Host file entry for client23 and you should be all set.

/etc/hosts

no,i dont want to do this, i have lots of clients and i dont want to use /etc/hosts.

thats why i asked if there is any way to use the Description field instead of the Hostname field to feed a script command
or
where do i hack the util.c or snmp.c not to check the availability of the host via no ping or snmp query.

thx for your first reply, but i need a better workaround..

If the community string is blank, the device will not be polled for availability.

tried that..

wether i set the community string to blank or not, cactid still checks what i inserted at Hostname field (New Graph page) ....

Edit your device and post a jpeg of the screen at that moment.

Edit your device and post a jpeg of the screen at that moment.

here is the screenshot. so you see what Hostname it is.
the default snmp or ping check cant find that to check only if i modify named and /etc/hosts
i want to stop the availability check and let me graph whatever i want based on that name.

can you like hack snmp.c or util.c of cactid and put somewhere a variable USE_CHECK to be set either 0 or 1 to not check or to check the hosts before doing graphs on them..

thx.

Cacti 0.8.7 will include the ability to have host specific checks including "nocheck". My suggestion would be to just hang-on until we get the 0.8.7 stuff rolled out. Therefore, simply use the host file for now. I don't want to:

1) Rush 0.8.7
2) Hack Code

However, if you did want to "hack" the Cactid code, I would do it in poller.c. If you want to do some advance testing in 0.8.7, it would be good to have a new member of the beta team.

well, look what cactid.log says :

12/08/2004 03:04:04 PM - PHPSVR: Poller[0] PHP Script Server has Started - Parent is cactid
12/08/2004 03:04:04 PM - CACTID: Poller[0] ERROR: Problem initializing SNMP session 'Netland'
12/08/2004 03:04:04 PM - CACTID: Poller[0] WARNING: Unknown host Netland
12/08/2004 03:04:04 PM - PHPSVR: Poller[0] ERROR: Input Expected, Script Server Terminating

i dont want to put Netland in /etc/hosts or named, i have too many clients to graph to choose this as a workaround.
i just need cactid NOT to check the host getting Netland from Hostname field on the New Graph section.
where do i modify to not start the SNMP session routine nor trying to resolve the hostname ?

THX.

Do you want to disable the check for ALL servers?
