Credentials and Access

SSH Access

  • Please use your GEANT AD account(GEANT\dante.xxx or GEANT\Firsname.Lastname)to have ssh access and sudoer rights on the required servers.

Other Access

  • Required credentials are in the "GÉANT Dashboard v3" LastPass folder

Problems

New alarms are not appearing in the gui

Possible Cause: Traps not being processed by RabbitMQ

Analysis
  1. Open one or more of the following RabbitMQ management consoles.  (Credentials are in the "GÉANT Dashboard v3" LastPass folder)
  2. Scroll down to the "Nodes" section
  3. There should be 3 rows in the table and all status icons should be green (currently - there is a red bar showing a deprecated node - this will be removed when possible).  The expected node hostnames are:
    • prod-noc-alarms01.geant.org
    • prod-noc-alarms02.geant.org
    • prod-noc-alarms03.geant.org
Solution
  1. If one of the 3 nodes is failing or missing from the list, log into the failing server via ssh and restart the RabbitMQ service:
    • sudo systemctl restart rabbitmq-server
  2. After a minute or two the management consoles should show the cluster is restored.

Collectors have stopped working

Analysis

  1. Open https://net-alarms-monitoring.geant.org/d/hESYQotZz/correlation-services?orgId=1
  2. Scroll down to the "Collectors" panel
  3. Check that the graph shows a nonzero rate of traps being processes

Solution

  1. On each of the following servers:
    • net-alarms01.geant.org
    • net-alarms02.geant.org
    • net-alarms03.geant.org
  2. Log in via ssh and execute the following command:
    • sudo systemctl restart trap_collector

Possible Cause: Correlators have stopped working

Analysis

  1. Open https://net-alarms-monitoring.geant.org/d/hESYQotZz/correlation-services?orgId=1
  2. Scroll down to the "Collectors" panel
  3. Check that the graph shows the leader collector processing a non-zero rate of traps.  The current leader can be identified by the FORWARDER with state 2 in the "Raft States" panel.

Solution

  1. On each of the following servers:
    • net-alarms01.geant.org
    • net-alarms02.geant.org
    • net-alarms03.geant.org
  2. Log in via ssh and execute the following command:
    • sudo systemctl restart trap_correlator
