0.8.6.d missing hardware address/status/type in data query

Post by **TheWitness** » Tue May 03, 2005 5:49 am

No. Edit Host, then Click "Create Graphs", then Click "Green Circle". See if that makes the "Up/Down" reappear.

Maybe I'm a bit slow. I'm not using php-snmp, snmpwalk seems to work, MIBS=ALL is not set.

I haven't changed anything else since yesterday, why should up/down now reappear. I've tried this yesterday a few times. Am I missing something you suggested? I didn't reboot, because you wrote that this would only necessary if MIBS=ALL is set.

If MIBS=All is set and you clear it, you need to restart Apache. With some people, it's easier to simply instruct to Reboot.

Have you attempted refreshing with the Green Circle? If it restores the information, it is likely Cactid that is affecting the display.

I've refreshed the devices with the green circle several times since yesterday. No change. I don't get up/down, type or hardware address.

The new php-snmp package for fedora has just been released. So I changed the cacti settings to

$config["php_snmp_support"] = function_exists("snmpget");

Cacti Variables
Operating System: unix
PHP SNMP Support: yes

No luck. After hitting the green button there are still only the numerical values for status/type and no hardware address!

I get the right values with snmpwalk (see first post), thus the MIB files can't be the cause. What's left, what more can I check?

cacti output for status

Where is the fix? I couldn't find anything related in cvs or matis.

I'm confused!

Sorry Ralf, I've been working too many hours between work, home and Cacti and misread your post. I don't have too much time this week. Did I have you try backing off lib/snmp.php 1 version. Give it a show and see what happens.

Ok, going back to snmp.php from cacti 0.8.6c seems to solve the problem! Status/Type and HW Address is back!

1 Up GigabitEthernet1/1 Gi1/1 $serverA ethernetCsmacd(6) 1000000000 00:00:0B:FD:84:BD:80
2 Up GigabitEthernet1/2 Gi1/2 $serverB ethernetCsmacd(6) 1000000000 00:00:0B:FD:84:BD:81
3 Up GigabitEthernet2/1 Gi2/1 $serverC ethernetCsmacd(6) 1000000000 00:00:0D:65:04:DA:94

Should I open a bug report, or do you want to have a closer look at this first? Could I run into problems with this version of snmp.php in connection with cacti 0.8..6d?

BTW: I highly appreciate the time you dedicate to cacti and the users in this form!

Money does help

As far as a bug report, that is not required. Would you be willing to try another version (patch) though. I believe I know what's wrong, but I need someone like yourself to test. I will attach the file, but then I have to goto work. When I get off work, you will either have turned in the day, or out somewhere having coffee with friends.

Weekends are much better for me to work with overseas users. Say, Saturday morning our time.

I just tried this patch, but get an error when adding a device or reloading the "SNMP - Interface Statistics" data query :

Code: Select all

Warning: Cannot modify header information - headers already sent by (output started at /cacti/cacti-0.8.6d/lib/snmp.php:215) in /cacti/cacti-0.8.6d/host.php on line 70

Ok, I have to get to this after hours. Rollback for now.

Removing the last (blank) line of snmp.php removed the error, but I still don't get status, hardware address and type.

Thanks for the quick response!

With the new snmp.php get a blank page and an error in the apache error log.

PHP Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/cacti-0.8.6d/lib/snmp.php:215) in /var/www/html/cacti-0.8.6d/graphs_new.php on line 45, referer: http://$IP/cacti/graphs_new.ph

I see that you changed this part of snmp.php. But I'm not the wolds best coder...

$o = 0;
foreach ($temp_array as $key => $val) {
$snmp_array[$o]["oid"] = ereg_replace("^\.", "", $key);
$snmp_array[$o]["value"] = format_snmp_string($val);
$o++;
}

I'll try to modify your changes, maybe I can get this working.

Weekends are much better for me to work with overseas users. Say, Saturday morning our time.

Tomorrow is a public holiday here in germany and I'll out of office until monday

So, I'll stay with smp.php v0.8.6c until next week.

Have a nice weekend!

Interesting. Unknown end of file marker. Try this one.
