Warning: Invalid Argument Supplied- snmp.php

[hgrueber]

Hi,

When adding devices into Cacti I receive the following warning messages in the console after walking via snmp:

Warning: Invalid argument supplied for foreach() in /usr/share/cacti/site/lib/snmp.php on line 277

Warning: Invalid argument supplied for foreach() in /usr/share/cacti/site/lib/snmp.php on line 483

Warning: Cannot modify header information - headers already sent by (output started at /usr/share/cacti/site/lib/snmp.php:277) in /usr/share/cacti/site/host.php on line 164

I have checked snmp.php and line 277 refers to:

foreach($banned_snmp_strings as $item) {
if(strstr($value, $item) != "") {
unset($temp_array[$key]);
continue 2;

Also line 483:

foreach($banned_snmp_strings as $item) {
if(strstr($string, $item) != "") {
$string = "";
break;

Line 164 in host.php refers to:

header("Location: host.php?action=edit&id=" . (empty($host_id) ? $_POST["id"] : $host_id));^M

I can't see any errors in the cacti log.

It appears that Cacti is polling devices and graphing correctly however I'd like to fix these warning messages. Any suggestions on how to fix?

Versions:
snmp: 5.4.1
php-snmp: 5.2.6
apache2: apache2.2.11
rrdtool: 1.3.x
OS: Ubuntu 9.0.4
Cacti version: 0.8.7e with current official patches and plugin architecture installed - no plugins installed/enabled.

Poller is cmd.php.

I found the answer to my problem.

PIA 2.5 causes these errors when installed with 0.8.7e + official patches.

Argh I regret installing PIA 2.5 now.

So basically I either wait for a new version of PIA 2.5 or uninstall PIA 2.5. Is there a way to uninstall 2.5 or do I have to reinstall Cacti from scratch?

Reinstalling the original cacti 0.8.7e FILES + official patches will work fine.

Yeah cheers BSOD.

I ended up reinstalling 0.8.7e, installing PIA 2.5 + weathermap and then I applied the official 0.8.7e patches.

All good now.

There is an updated PIA 2.5 at the top of this forum which should fix the issues.
