SMTP email alerts stopped working

I recently updated to Observium CE 26.1.14545. Since the update, I am no longer receiving email alerts. I selected an alert from the dashboard (4354) and ran ./test_alert.php -a 4354. This is the response I get in the shell: Oops! Something went wrong! You may want to report this to the Observium developers. Call to undefined function get_entity_group_names() in /opt/observium/includes/notifications.inc.php:97 Stack trace: #0: (unknown function) called at [/opt/observium/includes/notifications.inc.php:97] 92: $device = device_by_id_cache($entry['device_id']); 93: $entity = get_entity_by_id_cache($entry['entity_type'], $entry['entity_id']); 94: $alert = $alert_rules[$entry['alert_test_id']]; 95: 96: // Get device group memberships for alert routing 97: $device_groups = get_entity_group_names('device', $device['device_id']); 98: 99: // Get entity group memberships for alert routing 100: $entity_groups = get_entity_group_names($entry['entity_type'], $entry['entity_id']); 101: 102: /// DEVEL #1: alert_generate_tags called at [/opt/observium/includes/notifications.inc.php:26] 21: */ 22: function alert_notifier($entry, $type = "alert", $log_id = NULL) { 23: 24: $device = device_by_id_cache($entry['device_id']); 25: 26: $message_tags = alert_generate_tags($entry, $type); 27: 28: //logfile('debug.log', var_export($message, TRUE)); 29: 30: $alert_id = $entry['alert_test_id']; 31: #2: alert_notifier called at [/opt/observium/test_alert.php:56] 51: 52: $entry = dbFetchRow($sql, [$options['a']]); 53: print_debug_vars($entry, 1); 54: 55: // Generate alerts and insert them into the queue 56: $ids = alert_notifier($entry); 57: } elseif ($options['c']) { 58: // Test by contact id 59: $ids = []; 60: 61: // Fetch notification example from json file Any assistance is appreciated.

No longer have SVN access

Hi guys, We have the Enterprise license and installed an Observium poller right after the main installation. Unfortunately, we can’t install any more poller instances because SVN access is no longer available. Is there perhaps a workaround, or any explanation as to why SVN access is no longer available? Or has the SVN user's account expired? Any help is welcome. ---------schnip------------ 6.

Fix for hdarray
by Chris James 17 Apr '26

17 Apr '26

We have continued to have an issue where PERC controller status is flagged as failed on pretty much all our Poweredge Rx20, Rx30, Rx40, Rx50, Rx60 servers. We finally got to the bottom of it today. Please can the following be corrected. Root Cause: perccli64 requires an open stdin to function correctly. When it runs with stdin closed (<&-), it returns Status = Failure instead of querying the controller. The Observium agent script closes stdin as a security measure (exec <&- 2>/dev/null) before running all local scripts, so every time the agent ran our hdarray script via the socket, perccli silently failed. The Fix: Add </dev/null to all four perccli calls in the hdarray script so the binary gets a valid (empty) stdin rather than a closed file descriptor: $CLI show nolog </dev/null 2>/dev/null $CLI /c${ctrl} show nolog > $RAID 2>&1 </dev/null $CLI /c${ctrl}/vall show nolog > $RAID 2>&1 </dev/null $CLI /c${ctrl}/eall/sall show nolog > $RAID 2>&1 </dev/null What made this so hard to diagnose: The script worked perfectly in every direct test (setsid, bash -x, env -i, running as root via ssh) because all those methods leave stdin open. It only failed via the agent socket where stdin was closed - exactly replicating production conditions was key. Many thanks, Chris

fix for nvidia GPU load at 0% but reported as critical
by Chris James 16 Apr '26

16 Apr '26

We run a number of machines with nvidia GPU cards and notice that when the load is reported at 0% - which can happen when the machine is idle - its flagged as critical in Observium. The fix is as follows: In the ./includes/polling/unix-agent/nvidia.inc.php file change the utilization.gpu and utilization.memory discover_sensor calls from: ['limit_high' => 100, 'limit_low' => 0] To: ['limit_high' => 100] This the file looks like: <?php /** * Observium * * This file is part of Observium. * * @package observium * @subpackage poller * @copyright (C) Adam Armstrong * */ global $agent_sensors; if (!safe_empty($agent_data['nvidia']['smi']) && $nvidia = parse_csv($agent_data['nvidia']['smi'])) { $invalid = [ '[Not Supported]', 'N/A', '[N/A]' ]; print_cli_heading("nvidia-smi", 3); foreach ($nvidia as $card) { $descr_card = "Nvidia Card " . ((int)$card['index'] + 1) . ": " . $card['name']; print_cli_heading($descr_card, 4); if (!in_array($card['temperature.gpu'], $invalid)) { $index = 'temperature.gpu.' . $card['index']; $descr = $descr_card; discover_sensor('temperature', $device, '', $index, 'nvidia-smi', $descr, 1, $card['temperature.gpu'], ['limit_high' => 100], 'agent'); $agent_sensors['temperature']['nvidia-smi'][$index] = ['description' => $descr, 'current' => $card['temperature.gpu'], 'index' => $index]; print_cli_data("temperature.gpu", $card['temperature.gpu'] . "C"); } if (!in_array($card['power.draw [W]'], $invalid)) { $index = 'power.draw.' . $card['index']; $descr = $descr_card; discover_sensor('power', $device, '', $index, 'nvidia-smi', $descr, 1, $card['power.draw [W]'], [], 'agent'); $agent_sensors['power']['nvidia-smi'][$index] = ['description' => $descr, 'current' => $card['power.draw [W]'], 'index' => $index]; print_cli_data("power.draw", $card['power.draw [W]'] .

""); } if (!in_array($card['utilization.memory [%]'], $invalid)) { $index = 'utilization.memory.' . $card['index']; $descr = $descr_card . " Memory Load"; discover_sensor('load', $device, '', $index, 'nvidia-smi', $descr, 1, $card['utilization.memory [%]'], ['limit_high' => 100], 'agent'); $agent_sensors['load']['nvidia-smi'][$index] = ['description' => $descr, 'current' => $card['utilization.memory [%]'], 'index' => $index]; print_cli_data("utilization.memory", $card['utilization.memory [%]'] .

Is there a way to send an alert on billing when it's at n% of the allotment? I had a look through the alertingbut I can't see how this would be done. I'm on 26.3.14656 (rolling) (3rd March 2026) Thank you, -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net

Adding new OS to central but still getting generic
by Bryan E 13 Apr '26

13 Apr '26

Hello, I'm trying some thing. First I have a Central Observium server hosting the DB and graphs. My devices are polled via another Debian-poller who's the only one talking to central observium. I've added a stormshield on observium but it comes as a generic device, so I've tried to follow the guide to add a new OS (https://docs.observium.org/developing/add_os/) my new file /opt/observium/includes/definitions/os/stormshield.inc.php is like the following: $os = "Stormshield"; $config['os'][$os]['vendor'] = "Stormshield"; $config['os'][$os]['text'] = "Stormshield OS"; $config['os'][$os]['type'] = "firewall"; // Set type in polling os $config['os'][$os]['sysObjectID'][] = ".1.3.6.1.4.1.11256.1"; $config['os'][$os]['sysDescr'][] = "/^NS-BSD/"; $config['os'][$os]['mibs'][] = "STORMSHIELD-PROPERTY-MIB"; The MIBS seems OK on /opt/observium/includes/definitions/mibs/stormshield.inc.php redirecting to stormshield folder My folder /opt/observium/mibs/stormshield/ is filled with MIBS but still... I might be missing something because when I execute ./discovery.php -h mydevice_ID -m os on the Debian-Poller it still comes as generic +-------------+------------------------------+ | OID | | +-------------+------------------------------+ | sysDescr | NS-BSD SNSS1XXXXXXX amd64 | | sysObjectID | .1.3.6.1.4.1.11256.1.20.7 | +-------------+------------------------------+ o OS Type generic o OS Group unix

NuDesign SNMP Agent for Windows
by Tony Guadagno 03 Apr '26

03 Apr '26

Hi, i was wondering if anyone in the community has any experience with using this snmp agent on windows servers? I am frustrated (like we all are) with Microsoft's lack of snmpv3 support as well as some notable omissions from their native snmp agent (for example, lack of mounted volume support as well as service visibility). Has anyone used this agent with Observium?? is it better than the native agent?? thanks in advance https://www.snmp4windows.com/SNMP/snmpv3-agent-service-for-windows/

how can i alert when link is up but eigrp peer (next hop) is down
by Tony Guadagno 02 Apr '26

02 Apr '26

hi, I am hoping someone can give me some suggestions on how to alert when my Cisco router's interface is up/up but the other side is not responding. I just discovered that I have been running on a backup line for a while at one site and did not know it because the primary link did not go "down" is there anything I can do with monitoring eigrp peers etc. It did occur to me that if I set up an sla on the router, I might be able to leverage that, but I would like a solution that did not involve more config on the router. thanks in advance
