SNMP Trap Import
by Kevin Wormington 04 Apr '16

04 Apr '16

Hi, I’m new to Observium (paid version) and am working toward replacing Zabbix completely with it. I see that there is some old/unsupported support for importing LinkUp/LinkDown traps from snmptt in snmptrap.php. I’m going to be testing it out in the next few days and making any required fixes to get it going with current versions. I have also though about implementing some type of mechanism to log/alert on various traps other than LinkUp/LinkDown such as ColdStart, etc. I am curious if there is any interest in that from other users and any input on how people would like to see it implemented and if anyone else is currently using it. Thanks, Kevin

Missing TenGigabit interfaces on Cisco WC-C4900M
by Per Jorgensen 03 Apr '16

03 Apr '16

Hi all First of all thank to the team of developer for making this program, and making it better and better everyday, love the look and ease of use. But I have run into a problem with a Tengigabit ethernet device I newly added into my Observium v. 0.12.8.3360. it seems that every thing get detected alright, except all the TenGigabitEthernet, interfaces dont show up anywhere in Observium, all other interfaces on that device gets detectet allright, and I can see the interfaces in the ports tab on the device, but not the TenGengigabit interfaces. btw: the device is a Cisco WS-C4900M Is that because Cisco WS-C4900M is not a supported device , or should I do some config changes to get TenGigabitEthernet to work ? if the WC-C4900M is not supported, how can I then contribute with information on the device , and help to then this device supported ? Best Regards Per Jorgensen

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
