Overview

You have applied a change in your servers, added/subtracted servers from the Lithium farm, or you just want to check if the status of all servers in the nodes is correct for troubleshooting purposes. The following article contains the basic checks you must go through to narrow down issues related to the service's health.

Information

The Expected Outcomes below are just given as examples and are meant to be taken as a reference. The actual outcome may be different depending on the services installed and configured

1. Change the user to textpass by executing the following command:

   sudo su - textpass

   
   
   
2. SSH as textpass into all nodes and execute the following commands:
   

   tp_status

   • Expected outcome (Traffic element):
     
     [textpass@TrafficNode ~]# tp_status
     PROCESS STATE UPTIME
     textpass   operating 0 days, 0:04:34.87
     tp_faf       operating 0 days, 0:04:34.77
     tp_pbc     operating 0 days, 0:04:34.67
     tp_fclient operating 0 days, 0:04:36.00
     tp_mgrd  operating 0 days, 0:04:35.00
     
     
     
     
3. On a Traffic node, execute the following command (as textpass):
   

   m3ua_link

   • Expected outcome (Traffic element/ Firewall) :
     
     [textpass@Firewall ~]$ m3ua_link
     Reading information from localhost:11861
     SGP-NAME OPSTATE SCTP-OPSTATE APC-OPSTATE VPC-OPSTATE
     M3UA-1A    up           established       active             inactive
     M3UA-2A    up           established       active             inactive
     M3UA-3A    up           established       active             inactive
     M3UA-4A    up           established       active             inactive
     
     
4. Execute as root
   

   ps -eaf | grep -i stv | grep -v auto

   • Expected Outcome (Non MGR Node):
     
     [textpass@NON-MGR-Node ~]$ ps -eaf | grep -i stv | grep -v auto
     textpass 1883 1 0 Oct15 ? 00:00:38 /usr/bin/perl /usr/TextPass/bin/stv_poller --start
     textpass 26429 32161 0 11:55 ? 00:00:00 /usr/bin/perl /usr/TextPass/bin/stv_poller --start
     textpass 32158 1883 0 Oct18 ? 00:00:03 /usr/bin/perl /usr/TextPass/bin/stv_poller --start
     textpass 32159 1883 0 Oct18 ? 00:00:03 /usr/bin/perl /usr/TextPass/bin/stv_poller --start
     textpass 32161 1883 0 Oct18 ? 00:00:21 /usr/bin/perl /usr/TextPass/bin/stv_poller --start
     
     
     
     
5. On FWL node, monitor syslogs for any errors:
   

   tail -f /var/log/messages

   
   
   
6. Check the NTPD service is running:
   

   systemctl status ntpd

   
   
   
7. Check the SNMPD service should be running:
   

   systemctl status snmpd

   
   
   
8. As root, check the network service should be running:
   

   systemctl status network

   

If you are getting errors in any of these logs, please create a support ticket with the result of the execution of the last 4 commands so we can analyze deeper your issue.
