How to add support for new device/type?
by Jens Bürger 02 Apr '16

02 Apr '16

Hello everyone, first: the mailing list archive is somehow not online: http://postman.memetic.org/pipermail/observium/ So I couldn’t have look at the archive to see if my question was answered recently. I would like to add support for my PBX (Siemens HiPath 3000 series, model 3800) to Observium. There this a file containing MIBs available and someone also did preliminary support for Nagios: https://exchange.nagios.org/directory/Plugins/Hardware/Network-Gear/Siemens… So I had a look at this site: http://www.observium.org/docs/developing/add_os/ The file os.inc.php doesn’t exist, but a definitions.dat instead which is a binary file. So I wonder where to start i.e. getting some kind of device template I can start with? Thanks a lot, Jens

switchmap re: host<-->port L2/L3 matrix
by Rob VanHooren 02 Apr '16

02 Apr '16

indeed, it would be quite handy to have information about the end hosts. obviously not a full scrape of them for monitoring, but that they exist, what they are, and where. ideally, there could be some observium-style SPoG embrace of Pete Siemsen’s switchmap ( https://sourceforge.net/projects/switchmap/ ) his is a wonderfully useful tool in terms of how much information it packs onto one page, but visually … it’s rather archaic. $0.02 R. > On Apr 2, 2016, at 02:47, observium-request(a)observium.org wrote: > >> Adam / Tom / Justin / David /etc/ >> >> {various discussion about port matrix L2 L3 presentation etc…} >>

patch: show ip associated with mac
by Justin Cinkelj 02 Apr '16

02 Apr '16

Hi I here and there search for IP address belonging to certain MAC address. Below is a tiny patch to show that info in observium. Data is read from arpwatch datafile (path to datafile is set in config.php): // enable arpwatch $config['arpwatch']['datafile'] = "/var/lib/arpwatch/arp.dat"; And once IP is known, reverse DNS name is informative too. Patch acceptable for inclusion? BR Justin diff --git a/html/ajax/entity_popup.php b/html/ajax/entity_popup.php index 86c2b43..ef2fe18 100644 --- a/html/ajax/entity_popup.php +++ b/html/ajax/entity_popup.php @@ -73,6 +73,25 @@ switch ($vars['entity_type']) } else { echo 'Not Found'; } + // search for mac in arpwatch datafile + $aw_on = array_key_exists("arpwatch", $config) && + array_key_exists("datafile", $config["arpwatch"]) && + $config["arpwatch"]["datafile"]; + if ($aw_on) { + // lines are formated: mac ip timestamp name + $aw_file = "/var/lib/arpwatch/arp.dat"; + $aw_data = file_get_contents($aw_file); + $aw_data = explode("\n", $aw_data); + for ($line = 0; $line < count($aw_data); $line++) { + if (strpos($aw_data[$line], $vars['entity_id']) !== false) { + list($aw_mac, $aw_ip, $aw_timestamp, $aw_name) = preg_split("/\s+/", $aw_data[$line]); + echo "<br>arpwatch: " . $aw_ip .

Alerts based on a sudden increase of packets per second
by Stephen Fulton 31 Mar '16

31 Mar '16

Hi all, Is there a way to generate an alert when an interface has a significant increase of packets per second, compared to a previous recorded amount? Is there a way to compare deltas? I'm looking to identify interfaces which may be experience a DoS situation. Thanks, -- Stephen

LDAP/AD Groups
by Spencer Ryan 31 Mar '16

31 Mar '16

Hey Tom, Can you log into an AD setup you have with /debug/ and tell me what this says? LDAP[UserID][XXXXX] In our environment I had to patch ldap.inc.php to get the UID to map properly (and thus apply groups). Before that the UserID would always be -1. I'm trying to figure out if I had some bad config.php settings, or if it's actually broken and I can send you guys the patch I wrote. Thanks! *Spencer Ryan* | Senior Systems Administrator | sryan(a)arbor.net *Arbor Networks* +1.734.794.5033 (d) | +1.734.846.2053 (m) www.arbornetworks.com

Solaris Filesystems not being read correctly
by Dano, Leo 31 Mar '16

31 Mar '16

Good morning all, Linux nodes read fine, but Solaris is not reading the partition size correctly. Example: / partition going directly onto the Solaris host shows is to be 5.7TB Observium shows it as much smaller 1.78tb Any thoughts? Or is Solaris not fully supported? Thanks, ----------------------- Leo Dano
