Build 2738: Alarm config for ANDing of process states of two different processes is not supported

[Ankit Jain]

I was trying to configure an alarm for the following condition:

Condition: when process1 and process2 are both down then only I should raise an alarm.

Say contrail-dns.state=DOWN AND contrail-named==DOWN -> Raise a configured alarm...

I see the above condition is not configurable with the current alarm implementation.

Please check if we can support this.

I tried the below, this did not help as both the below conditions seem to be same.

and_list:

[
 •
{
 ◦ operation: "!=",
 ◦ operand1: "NodeStatus.process_info.process_state",
 ◦ vars:
[
 ▪ “”contrain-dns"
 ◦ ],
 ◦ operand2: ""PROCESS_STATE_RUNNING""
 • },

[
 •
{
 ◦ operation: "!=",
 ◦ operand1: "NodeStatus.process_info.process_state",
 ◦ vars:
[
 ▪ “”contrain-named"
 ◦ ],
 ◦ operand2: ""PROCESS_STATE_RUNNING""
 • },

Since process_info is a list, we cannot support this configuration. However, we are planning to change process_info to map with process name as the key [for R3.2]. With process_info being a map, you would be able to configure the alarm mentioned in the description.
