Is there an easy way to query a DFM server remotely? I'd like to grab some data on demand (Current CPU). I could do that via SNMP without too much trouble, but I'd rather not let all the clients directly poll the filers.
The DFM server already has that information, and I can poll it on the machine itself with something like 'dfm report filers-ops <filer>'. I'd rather let the clients hit this machine so there's no performance impact on the filers if something goes wrong. Is there a way of getting that same data from a remote host without setting up accounts and automated logins? I thought I might be able to run the dfm software on the client directly, but if I can, I'm missing how to specify the server that it contacts...
The web reports are fine, but I don't want to scrape them through the normal display. If I can get the raw data from the DFM server via http/snmp/other, that would be good.
Thanks.
You can hit the DFM server with an HTTP request to send you the data it would have shown you in the filers-ops report, but in a different form, such as comma-separated values.
Use a URL like
http://%7Bdfm-server%7D:8080/dfm/report/filers-ops?output-format=xls
You can pass arguments to filter the list by filer, or by group, however you like.

Great. That'll work perfectly. Grabbing it as a csv will make it easy for my needs.
And now I understand the relationship with the reports that I see on screen.
Is the web query format documented somewhere? For instance, I don't need it, but is there an equivalent to the -q option for removing the header lines?
Thanks!

There's a little bit of documentation in the online help text. See, for example, "dfm report view help".
Once you know the trick, you can map from the documentation:
The options are -g <group-id or group-name> -F <output-format> -l <lines> -q (quiet)
To the URL equivalent:
http://localhost:8080/dfm/report/filers-ops?output-format=xls&quiet=1

Sweet. That helps considerably.
Thank you again.
Yes, Operations Manager (formerly known as DFM) is a licensable product. One of our folks will get in touch with you.
Thanks Subbiah
