17 Jun '15

Hi All, hoping someone has seen this issue I’m having for some mad reason the HDD temperature sensor on one our of servers keeps disappearing ? but whats mad is the event log is showing the Entity as BLANK ? and another mad thing I’ve noticed is when it gets re-added or updated the HIGH and LOW keep getting adjusted to 0, so i have to all the time go and manually adjust the values? is it possible a problem with hddtemp, observium, or something else I’m just missing? I have attached a screenshot showing what I mean regards Simon

Rsyslog after upgrade from 13.10.4585 to 14.4.XX
by Koen Claes 16 Jun '15

16 Jun '15

Hello, I am currently using an installation of Observium that works very well. I installed rsyslog according to this link : http://www.observium.org/wiki/Rsyslog_Syslog_Server I tried upgrading it for the first time to the most recent version, and everything seemed to work fine, but after a few hours syslogs stopped showing in the web interface. They do still arrive to the machine according to tcpdump. I rolled back the server and it worked again, even for a week now. After upgrading it again it does the same, works for a while and then stops. So I have 2 questions: 1: Where are syslogs saved? In the mysql database? 2: Did anything change regarding to syslog in the major version? I did notice a new logs folder. Thanks This message has been scanned for malware by Websense. www.websense.com

A same rsyslog config for observium + remote logging
by Jason Lixfeld 16 Jun '15

16 Jun '15

I was working on trying to get my rsyslog configuration working with observium as well as preserving my configuration for logging inbound logs to files based on the sender’s hostname so Splunk could eat them. It was a bit of a pain, so I thought I’d share incase anyone else found it useful: # /etc/rsyslog.d/30-remote.conf # # Based on a default rsyslog.conf file from Debian Jessie (8) # module(load="omprog") module(load="imtcp") module(load="imudp”) template(name="observium" type="string" string="%fromhost%||%syslogfacility%||%syslogpriority%||%syslogseverity%||%syslogtag%||%$year%-%$month%-%$day% %timereported:8:25%||%msg%||%programname%\n") template(name="hostname" type="string" string="/var/log/remote/%HOSTNAME%.log”) ruleset(name="remote"){ action(type="omprog" binary="/opt/observium/syslog.php" template="observium") action(type="omfile" dynafile="hostname") } input(type="imtcp" port="601" ruleset="remote") input(type="imudp" port="514" ruleset="remote”) #<EOF>

MySQLi extension at r6455 (professional edition).
by Mike Stupalov 16 Jun '15

16 Jun '15

Hi, today added a new feature with ability to use modern php mysqli extension for db connections. It will not add new ponies in your piggy bank, but will give us opportunity to refuse in the future from obsolete php mysql extension. Currently new code will work ONLY if you manually add in config.php option: $config['db_extension'] = 'mysqli'; Also now added some new configurable options for db connections: $config['db_extension'] = 'mysqli'; // The PHP MySQL extension to use ('mysql' or 'mysqli') #$config['db_port'] = ''; // MySQL port (leave blank for default port: 3306) #$config['db_socket'] = ''; // Path to the socket (leave blank for default socket) #$config['db_persistent'] = FALSE; // Whether persistent connections should be used or not. WARNING use at own risk! #$config['db_compress'] = FALSE; // Use compressed protocol for the MySQL connection Please test new options and especially mysqli extension and report here (or in jira) about your success story ;) -- Mike Stupalov http://observium.org/

SNMPv3 with AES256
by Thiedek, Vic 15 Jun '15

15 Jun '15

Greetings! Does Observium support AES256 for SNMPv3 for Cisco Devices? Testing with SHA / AES128 SNMPv3 Authentication Successful Testing with SHA / AES256 SNMPv3 Authentication Fails I would use AES128, but the environment (750+ devices) was already setup for AES256. Thanks in advance! Vic

Location to request to add a MIB?
by Jason Lixfeld 15 Jun '15

15 Jun '15

I understand fully that MIB addition are on a best effort basis, especially for the obscure ones that might only matter to one person out of Observium’s entire install base :) So, where would I submit such a request for a MIB to be added? Here or JIRA? Elsewhere? Thanks!

Missing graph data
by Jason Vanlandingham 15 Jun '15

15 Jun '15

I had a problem with the machine Observium is running on. The CPU fan/heatsink fell off. After I got the machine up again on the evening of 11 June, the CPU Temp graph showed normal temps in the 30-45 range for months, then a big spike up to 115. (eek!) But at least the server came back to life, and I still had all my data. Everything still seems to be running OK, but all of a sudden there is now no data at all in the CPU temp graph before ~1:00AM 12 June. From this machine I get temp readings for CPU temp, Motherboard temp, and 4 other "temp#" listings. "Temp1" and "Temp3" still seem to have the data they should, but the others are missing. One thing I did change after the recovery: I noticed the time zone on the server was set to US Eastern, and I changed it to US Central. I would think if that was the cause of my problem it would hit a lot more of the data.

Roadmap for further alerting features?
by Jason Lixfeld 14 Jun '15

14 Jun '15

Hi, Curious whether or not there is a roadmap to support alerting on syslog messages or SNMP traps? I have these really ugly syslog power supply alerts from Splunk that I’d love to get rid of :) Thanks!
