[rock100773]

Hello,

Am running:
cacti version 0.8.7g
OS: CentOS release 5.2
PHP: PHP 5.1.6
--------

I just installed the latest cacti discovery plugin, http://docs.cacti.net/plugin:discovery#discovery which is working fine however am seeing duplicates hostnames or ips whenever discovery runs again after first polling takes place. Can someone please help with this issue or offer suggestion on fixing this?

I also check this forum posts but no answer was posted, http://forums.cacti.net/viewtopic.php?f=14&t=42122

Hi,
I am on release 1.5 of the discovery plugin using cacti 8.7h and v3 of the PIA.
I am seeing duplicated host entries in my devices list. I have performed a clean of all the hosts so that no hosts exist and it still creates them. I had thought that it was picking up the same host on different IP's (Which is doing for hosts that have multiple ips) but it's also doing it for hosts that only have one interface.

Any ideas?

Thanks

Does this happen for ALL discovered hosts or for some of them only?

HI Sorry for the late reply, didn't have the email responder on. It seems to happen for only some hosts.

THanks,

Hi I am still seeing this. It seems like the system description field is being ignored and hosts are still being added even when they have a different IP.

I noticed that Nothing was being populated in the plugin_discover_hosts table when the discover plugin ran.

I have Found a fix that solves my problem by editing the findhosts.php

Bad Code -

Code: Select all

$isDuplicateSysName = sizeof(db_fetch_assoc("SELECT * FROM plugin_discover_hosts WHERE sysName='" . $snmp_sysName[0] . "'"));

By having it look up the description from the host table it didn't add hosts that had the same system description already present.

Fixed code -

Code: Select all

$isDuplicateSysName = sizeof(db_fetch_assoc("SELECT * FROM host WHERE description='" . $snmp_sysName[0] . "'"));

Let me know what you think of this change.
