Alert checkers triggering on down/0 speed interfaces
by Ryan, Spencer 22 Oct '19

22 Oct '19

Since updating to 10134 we've seen some odd behavior out of our high interface utilization alerts. The alert itself is very simple, device matches *, entity is ifType equals ethernetCsmacd, and the test conditions are any of: ifInOctets_perc ge 80 ifOutOctets_perc ge 80 Which has worked fine forever. Now it's throwing alarms on an odd mix of devices (UBNT, Palo Alto, Arista, Kemp VLM, Infoblox) for ports that are down/down loopbacks or HA interfaces not connected. All of the ports it is alarming on show this in the data (Speed 0, and down/down): ifSpeed=>0 ifHighSpeed=>0 ifOperStatus=>down ifAdminStatus=>down Any idea what changed or why it's alarming on these now? I'm guessing its trying to do the 80% math on....0 but I'd imagine that shouldn't even run if the port is admin+operationally down. This is a mgmt interface on an arista (which is unconnected and admin down): https://pastebin.com/JsNvre40 As you can see the *_perc calcs are 0, it almost seems some kind of divide by 0 error. Thanks in advance!

False Positive Alert if sensor_value is "NULL" / "FALSE"
by Klimek, Denis 21 Oct '19

21 Oct '19

Hey all, is there any way to check with an alert condition if the return value for i.e. is "NULL" and/or "FALSE"? I have the case that we removed SFP+ transceivers from Extreme devices and the device is now not replying with any value for this OID check. The SQL database contains "0.00000" for the affected sensor. My current alert looks like: https://pastebin.com/f17b9gfW Example Alert (Web View): https://ibb.co/pfP27KD Mit freundlichem Gruß Stadtwerke Norderstedt Denis Klimek Carrier Manager & Professional Network Engineer IP-Systemtechnik Tel: +49 (0) 40 / 521 04 - 1049 dklimek(a)stadtwerke-norderstedt.de<mailto:dklimek@stadtwerke-norderstedt.de> www.stadtwerke-norderstedt.de<http://www.stadtwerke-norderstedt.de/>

Too many ports on a windows workstation
by Gianpaolo Racca 20 Oct '19

20 Oct '19

Hi everybody, I searched the docs for some hints about my problem but I didn't find anything. I'm very new to observium. I installed it in a docker container on a linux nas and I'm very happy with it. The main concern is that on a windows workstation (a nuc box) I have a LOT of interfaces listed: a lot of ethernet, a lot of tunnel interfaces. The other machines I monitor which are linux (computer or raspberry) don't show the same behaviour. Can you please point me in the right direction? Thanks and have a nice day, Gianpaolo

Fix for random logout
by Niklas Larsson 18 Oct '19

18 Oct '19

Hi, I spent some time figuring out why I got randomly logged out from the webpage and submitted a patch to https://jira.observium.org/browse/OBS-3132 Basically it was the session_regenerate_id() call that caused it, so I adopted the https://www.php.net/manual/en/function.session-regenerate-id.php suggested way. Well it works for me, try it out if you have the same issue. /niklas

Failure in notification of syslog alerts of the Ob server itself
by Shekhar Basnet 17 Oct '19

17 Oct '19

Hello, Observium is setup to email syslog alerts and it is doing so without any issues of all devices. I have a requirement to email some log alerts of the Observium server to the network team. I did the usual stuff of adding syslog rule and associating with a contact address. The logs (/var/log/messages) are matched by this syslog rule. I can see those matched lines in the Ob GUI. Yet strangely, an email is never triggered. Initially I thought it could be due to the log message and so I tried matching some other log lines, but always the log messages are matched by the syslog rule but email is never triggered. The contact address gets emails of all other alerts. Is there some other settings to enable Observium to email logs of it's own? Am running rsyslog and postfix on the Ob server. [root@observium sbasnet]# rsyslogd -v rsyslogd 8.24.0-34.el7, compiled with: PLATFORM: x86_64-redhat-linux-gnu PLATFORM (lsb_release -d): FEATURE_REGEXP: Yes GSSAPI Kerberos 5 support: Yes FEATURE_DEBUG (debug build, slow code): No 32bit Atomic operations supported: Yes 64bit Atomic operations supported: Yes memory allocator: system default Runtime Instrumentation (slow code): No uuid support: Yes Number of Bits in RainerScript integers: 64 [root@observium sbasnet]# postconf mail_version mail_version = 2.10.1 *Observium CE* 19.8.10000 (22nd August 2019) *OS* Linux 3.10.0-862.11.6.el7.x86_64 [amd64] (CentOS 7) *Apache* 2.4.6 (CentOS) OpenSSL/1.0.2k-fips mod_fcgid/2.3.9 PHP/5.6.40 mod_perl/2.0.10 Perl/v5.16.3 *PHP* 5.6.40 (OPcache: ENABLED) *Python* 2.7.5 *MySQL* 5.5.60-MariaDB (extension: mysqli 5.5.60-MariaDB) *SNMP* NET-SNMP 5.7.2 *RRDtool* 1.4.8 *Fping* 3.10 (IPv4 only) Thanks for help.

Kohler generator issue
by Tony Guadagno 15 Oct '19

15 Oct '19

Hi, a while ago you added support for the Kohler Generators. (thanks). I am noticing some issues. 1. The generator is listed as in “alarm status” all the time, no matter whats going on with the generator 2. When the generator goes under load, the observium state does not change to reflect that. I have attached 2 screen shots to illustrate as well as a txt file with the corresponding snmpwalk outputs. Also, Kohler has updated the mib, I have attached that as well, can you update the code base with this? thanks Tony

Tiny diff (adding probes)
by Aaron Finney 15 Oct '19

15 Oct '19

Hello maintainer friends, I'm not sure the proper protocol to request merging of small added bits, but I added two additional nprobe plugins, check_haproxy and check_ldap, to my install. The diff for probes.inc.php is below, but it also required a small modification to the check_ldap perl script (update hard-coded module dir). The LDAP probe I used is the version in the nagios-probe-contrib package Debian package, not the compiled C version distributed via the plugins tarfile from nagios.org; I used it because the contrib/perl version allows anonymous binding for just a basic service health check and doesn't require user/pwd/base-DN.

Mass Changes Ports Config (Alerting)

Hello, is there a way to set the alerts for all ports centrally to (ignore alerts) true? Would you like to set the alerts separately for each device in a later step. [cid:image001.png@01D58365.30219360] Mit freundlichen Grüßen Tobias Wissen
