hostname underscore
by Rob VanHooren 08 Nov '14

08 Nov '14

<oldgrump> underscore is an illegal character for a hostname, per RFC. you may thank a generation of miseducated Microsoft admins for thinking otherwise & polluting the world's DNS gene pool only to cause such untold suffering as this. dashes are perfectly fine because they're not illegitimate characters wrongly used by people who should have known better. bastards. </oldgrump> cheers, R. typogaphical errors courtesy of iPad.

smokeping ping tab now showing up on device
by Rory Schramm 07 Nov '14

07 Nov '14

H Guys, I'm having a problem with getting smokeping working with some of my devices. I have smokeping setup and it's working correctly ( I'm able to go to the smokeping cgi and see the graphs, etc). However the ping tab for smokeping isn't showing up for the device in observium. The device name is the same in both observium and smokeping. However, it's working fine for one of my switches but not the rest. I don't beleive it's a permission as I'm able to get it working with one of our switches. I added the following to my config for smokeping: $config['smokeping']['dir'] = "/var/lib/smokeping/";<mailto:observium@observium.org> The device in question is a cisco 3825 router. Observium CE 0.14.4.5229 Apache 2.2.22 (Ubuntu) PHP 5.3.10-1ubuntu3.15 MySQL 5.5.40-MariaDB SNMP NET-SNMP version: 5.4.3 RRDtool 1.4.7 Thanks, Rory ________________________________ The information contained in this transmission is privileged and/or confidential information intended for the use of the individual or entity named above.

SNMP Location string parsing
by Ulrik Ivers 06 Nov '14

06 Nov '14

Hi all, We use the geocoding functionality in Observium to place the devices on the front page map. All is working reasonably well. Today we set the SNMP sysLocation field locally in each device to street address ("Street, City, Country") We would like to be able to add "non-Geolocation" information to the sysLocation string without messing up the geolocation functionality. For example, we would like to add "Room 34, Rack 2" to the sysLocation. Is there functionality in Obervium to do this today? E.g. putting the extra information in "()" or other special characters? Regards, /Ulrik Ivers

Rivered Steelhead support
by Colin Stubbs 06 Nov '14

06 Nov '14

Hi All Riverbed MIB's are in both Observium stable and trunk... but there's no explicit Riverbed definition in os.inc.php. Was this removed at some point for a reason? Or is someone already working on Riverbed specific discovery and polling code? Thanks -Colin

Possible to create alerts for MySQL metrics contained in the MySQL agent?
by Hogan Whittall 06 Nov '14

06 Nov '14

We're trying to find a way to generate alerts on various MySQL metrics, it looks like all of the metrics are already in the monitor agent/graphs. What is involved in getting those metrics into the alerter/alert checker? This is for Pro. Thanks! -Hogan

Nexus 5596 polling slowness
by Daniel Bliss 06 Nov '14

06 Nov '14

Hello, Just curious if anyone else is seeing long polling times for Nexus 5596UP switches. Everything else in our deployment is responding in a timely manner and there are no bottlenecks on the Observium server at this point. ./poller.php: access2-2a.sj2 - 1 devices polled in 243.6 secs Polling times in the high 200 second range are not uncommon while most all of our other high port density devices are well under 30 seconds. If anyone has found a NXOS software version that works better than others please let me know. We have tried on various software version 5,6 and 7 releases. I can only imagine this is a Cisco issue but thought I'd ask here in case anyone solved it. Regards, Dan Bliss

Cisco ASA failover
by Carlos Martinez 05 Nov '14

05 Nov '14

I noticed that a pair of firewalls I had failed over about a month ago but the only thing showing in the logs of the device was that the mac addresses all changed. Is there a way to get better alerting on failover? I know the stateful failover are almost sub second but logs are generated. Not sure if you can monitor that with SNMP but figured I would throw that out there. Carlos

Basic Cisco Meraki hardware support
by Colin Stubbs 05 Nov '14

05 Nov '14

Hi Adam/All I may have missed how to make a more formal submission for hardware support, so if there is one let me know. However, I suspect the mailing list is probably a good arena for any criticism/pointers on what to do better/what not to do when attempting to add new device support. -- I’ve recently been involved in the installation of equipment and support for a mobile medical facility. We’ve used Meraki switches and access points for a number of reasons, not least of which is the instant monitoring/alerts capability, web based management, web based troubleshooting capabilities and easy provisioning of equipment when it needs to be replaced. As much as the Meraki web management portal is useful, it’s not necessarily always available in this facility and we needed a local management system/interface to monitor the equipment, alert local users to any failures/problems, and provide a quick and easy “view” for all of the ICT equipment within the mobile facility. So, I used Observium, but needed to add support for the Meraki components. Meraki provide an SNMP interface to their cloud management platform. It’s basically useless if talking directly to equipment as there’s currently no extra information you can extract from the devices themselves. The Meraki Cloud Controller MIB can be obtained here, https://n85.meraki.com/resources/MERAKI-CLOUD-CONTROLLER-MIB.mib Their cloud controller itself looks like the below. I don't really want to add this to Observium myself but have included the OID for detection and possible to for additional inventory collection at a later date. Strip it out if necessary. <pre class="prettyprint"><code>SNMPv2-MIB::sysDescr.0 = STRING: Cisco Meraki Cloud Controller SNMPv2-MIB::sysObjectID.0 = OID: MERAKI-CLOUD-CONTROLLER-MIB::cloudController DISMAN-EVENT-MIB::sysUpTimeInstance = INTEGER: -1685384396 SNMPv2-MIB::sysContact.0 = STRING: support(a)meraki.com SNMPv2-MIB::sysName.0 = STRING: dashboard.meraki.com SNMPv2-MIB::sysLocation.0 = STRING: 500 Terry Francois St., San Francisco, CA 94158, USA</code></pre> AP's basically look like this, SNMPv2-MIB::sysDescr.0 = STRING: Meraki MR18 Cloud Managed AP SNMPv2-MIB::sysObjectID.0 = OID: MERAKI-CLOUD-CONTROLLER-MIB::mr18 SNMPv2-MIB::sysORID.1 = OID: SNMPv2-MIB::snmpMIB SNMPv2-MIB::sysORID.2 = OID: SNMP-VIEW-BASED-ACM-MIB::vacmBasicGroup SNMPv2-MIB::sysORID.3 = OID: IF-MIB::ifMIB SNMPv2-MIB::sysORID.4 = OID: IEEE802dot11-MIB::ieee802dot11 SNMPv2-MIB::sysORDescr.1 = STRING: The MIB module for SNMPv2 entities SNMPv2-MIB::sysORDescr.2 = STRING: View-based Access Control Model for SNMP.

I don't have access to any of the security appliances at this time but the OID should be under .1.3.6.1.4.1.29671.2. anyway, so I believe Observium will auto-detect and add those too.

Print Interface Details - show other devices in the same subnet - need to exclude the private IP addresses ?
by Supun Rathnayake 05 Nov '14

05 Nov '14

Hi All, I have a small suggestion regarding the info displayed together with each interface under 'Port' => 'Detail' . There we noticed the observium displays all other devices on the same subnet from other devices at the last column of each interface irrespective of whether they are real IPs ( internet routable ) or Private IP addresses ( defined in RFC 1918 ). Although this feature is really good, we feel that if there is an option to exclude certain IP subnets from this selection, specially the private IP addresses it would make sense because we found there are lot of unrelated interfaces are getting listed ( about 50 items ) under this merely because of the fact that they are having the same IP addresses/subnets but which are completely different and isolated device interfaces in other VPNs which is common in IP VPN setups. We found the location where this logic is programmed, and we can easily changed the SQL query to accommodate this as follows ( *`ipv4_address` NOT LIKE '192.168.% etc. ) *shown below But it would be elegant if these excluding subnets could be defined as a config parameter and filter them here. This is just a suggestion, there may be better ideas out there with you guys What do you all think ? /opt/observium/html/includes/print-interface.inc.php : if ($port_details) { // *Show which other devices are on the same subnet as this interface* foreach (dbFetchRows("SELECT `ipv4_network_id` FROM `ipv4_addresses` WHERE `port_id` = ? AND `ipv4_address` NOT LIKE '127.%' *AND `ipv4_address` NOT LIKE '192.168.%*'", array($port['port_id'])) as $net) { $sql = "SELECT N.*, P.`port_id`, P.`device_id` FROM `ipv4_addresses` AS A, `ipv4_networks` AS N, `ports` AS P WHERE A.`port_id` = P.`port_id` AND P.`device_id` != ? AND A.`ipv4_network_id` = ? AND N.`ipv4_network_id` = A.`ipv4_network_id` AND P.`ifAdminStatus` = 'up'"; $params = array($device['device_id'], $net['ipv4_network_id']); foreach (dbFetchRows($sql, $params) AS $new) { if ($cache['devices']['id'][$new['device_id']]['disabled'] && !$config['web_show_disabled']) { continue; } $int_links[$new['port_id']] = $new['port_id']; $int_links_v4[$new['port_id']][] = $new['ipv4_network']; } } -- With Best Regards, Supun Rathnayake Lanka communication Services (Pvt) Ltd. 65C, Dharmapala Mawatha, Colombo 07.
