Monitoring Active/Standby failover

Edit /etc/alertd/alert.conf, bold lines added to the default file contents

  
  alert BIGIP_SOD_SODERR_SOD_STANDBY {  
          snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.14";  
          lcdwarn description="Unit going standby." priority="0"  
          email toaddress="LTM-alert@mydomain.com"  
          fromaddress="LTM1@mydomain.com"  
          body="LTM Failover event occured: Unit going to standby"  
  }  
  alert BIGIP_SOD_SODERR_SOD_ACTIVE {  
          snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.15";  
          lcdwarn description="Unit going Active." priority="0"  
          email toaddress="LTM-alert@mydomain.com"  
          fromaddress="LTM1@mydomain.com"  
          body="LTM Failover event occured: Unit going to active"  
  }  
  

This assumes you have postfix configured to forward mail to your relay.

Small nit... It should be

 
 alert BIGIP_SOD_SODERR_SOD_STANDBY {   
           snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.14";   
           lcdwarn description="Unit going standby." priority="0"; 
           email toaddress="LTM-alert@mydomain.com"   
           fromaddress="LTM1@mydomain.com"   
           body="LTM Failover event occured: Unit going to standby"   
   }   
   alert BIGIP_SOD_SODERR_SOD_ACTIVE {   
           snmptrap OID=".1.3.6.1.4.1.3375.2.4.0.15";   
           lcdwarn description="Unit going Active." priority="0"; 
           email toaddress="LTM-alert@mydomain.com"   
           fromaddress="LTM1@mydomain.com"   
           body="LTM Failover event occured: Unit going to active"   
   }   
  

Note the ';' (Semi-Colon) between the second alert (lcdwarn) and the third (email). (You need a semi-colon between each alert). Not obvious unfortunately. The alertd just logs into ltm that there's a problem at the email line otherwise.

yep, you're right, I missed that. Thanks!

While configured this, we are getting the below email "Subject: 010c0018". Is there any way we can change the subjet of the email?
