Description

This article explains why httpd and httpd-gk is not running on the secondary node in chassis cluster. J-Web management can be performed only on the primary node for the 0 redundancy group. The daemons referenced by J-Web do not run on the secondary node, so you will not find httpd and httpd-gk on the secondary node.

Symptoms

When checking the system process with the command, ‘show system processes extensive’ on the secondary node in a chassis cluster, httpd and httpd-gk are shown. But these processes are not shown in the output of 'show system processes extensive no-forwarding' .

Solution

This is expected behavior. The httpd and httpd-gk are not running on the secondary node. When using the command 'show system processes extensive' on secondary node, the output shows the processes on both nodes.


{secondary:node1}
root@SRX-node1> show system processes extensive
node0:
--------------------------------------------------------------------------
last pid: 18287; load averages: 0.08, 0.08, 0.08 up 10+01:51:16 21:31:02

1106 root 1 76 0 12408K 5744K select 0 38:08 0.00% license-check
...

The result of the command below actually shows the process on both nodes that match http:


{secondary:node1}
root@SRX-node1> show system processes extensive | match http
1521 root 1 76 0 13696K 5984K select 0 0:07 0.00% httpd-gk
2071 nobody 1 76 0 8892K 3584K select 0 0:02 0.00% httpd

If you want to check the process on node1 only, specify the node in the command:

{secondary:node1}
root@SRX-node1> show system processes extensive node 1 | match http

J-Web management can be performed only on the primary node for the 0 redundancy group. The daemons referenced by J-Web do not run on the secondary node. You will not find the httpd and httpd-gk on the secondary node.
