cDOT Tips 101 – Web Logs

Troubleshoot

With the transition to NetApp clustered Data ONTAP from 7-mode, a lot of end users are struggling not  only with new commands to learn, but also with troubleshooting a platform that admins are not familiar  with.

The most common mistake I see from admins, specially the newbies, is the lack of research and effort put  into a problem. Often times the problem is easy to fix, but you have to go find the root cause first.

While admins still stumble through the new commands, the first thing they should be doing during a troubleshooting exercise is to look for the logs. This may be obvious to some of us, but not to all. Fortunately cDOT allows for admins to look through the logs from a web UI as long as everything is configured properly, which removes some of the intimidation from new commands.

To access the logs for a node, you first need to:

  • setup a cluster management LIF
  • configure web protocol engine (HTTP or HTTPS (need certs))
  • allow chosen protocol through the firewall, if enabled
  • setup Service Processor Infrastructure (spi)
    • you can use vserver services web show to verify if it is enabled
  • cluster user account must be enabled for http access
  • access to the spi web service must be in place for your role (access-control)

Once everything is configured properly, you can navigate to:

Note: If you selected to use HTTPS and configured/imported certificates, the path will start with https instead of http as shown above.

If asked for credentials, use the credentials for the cluster user account.

  1. Great article! I’d also note that cluster admin (and the “admin” role by default) has “spi” access enabled by default, of course, in case you’re troubleshooting why access doesn’t work for a user account.

  2. Nice! I’ve got 8.3 (GA) installed, and noticed that when I just go to http:///spi , it gives me a really nice-looking view of the nodes and things I can view, without having to remember the names of the nodes or the paths of those logs. Give it a shot, it’s more convenient!
