Marvel - empty node stats section in Dashboard - JS error in console


(George Stathis) #1
  • Running 0.90.11
  • Marvel monitor machine and the cluster it monitors are separated
  • Installed Marvel the day after it was released and it was originally
    running fine (all panels filled with data)

Checked the dashboard again today (nothing has changed since it was
installed) and some panels in the dashboard like the node stats and the
indices stats are blank. I tried re-installing marvel on the monitoring
box, cleaned out all marvel-* indexes and even wiped out the data path
directory and let it re-build and the problem persisted.

So I took a look at the JS console and it shows the following errors (host
name redacted):

event.returnValue is deprecated. Please use the standard
event.preventDefault() instead. app.js?r=face658:5

I don't understand how this error just showed up without having changed
anything on the monitor machine or the cluster it monitors. Any clues are
welcome.

Hi George,
Just wondering if you've installed the Marvel plugin on nodes.

I think the Marvel dashboard is trying to access Marvel data but failing
because if you don't install the plugin on every node, the data isn't being
collected to be retrieved.

(Boaz Leskes) #3

Hi George,

I'm wondering why these search request return 400 bad request. My guess is
that it misses data.

Can you look at the ES logs on you server and see whether you have errors?

Also please run the following (note that it doesn't have a body, that's
intentional):

curl http://...:9200/.marvel-2014.02.20/_search?search_type=count

Does this return correctly?

Cheers,
Boaz

Yes, the plugin is definitely installed on every node of the cluster.
Installation was done in a repeatable and automated fashion (Ansible) and I
can verify the plugin presence on every node. Plus, as I mentioned, it
actually worked when I first installed it days ago.

[elasticsearch.marvel.1.traackr.com] All shards failed for phase: [query]

Looking at "failed to find mapping" made me think of the marvel mappings.
Sure enough, I did overwrite the settings but I messed up: instead of
re-naming my custom template I accidentally named it "marvel" essentially
clobbering the default template. No wonder it wasn't able to index the
fields properly.

I restored the template and it all works fine now.

Should have looked at the logs first. Thanks for point that out.

Hi George,

I'm wondering why these search request return 400 bad request. My guess is
that it misses data.

Can you look at the ES logs on you server and see whether you have errors?

Also please run the following (note that it doesn't have a body, that's
intentional):

curl http://...:9200/.marvel-2014.02.20/_search?search_type=count

Does this return correctly?

Cheers,
Boaz

Checked the dashboard again today (nothing has changed since it was
installed) and some panels in the dashboard like the node stats and the
indices stats are blank. I tried re-installing marvel on the monitoring
box, cleaned out all marvel-* indexes and even wiped out the data path
directory and let it re-build and the problem persisted.

So I took a look at the JS console and it shows the following errors

I don't understand how this error just showed up without having changed
anything on the monitor machine or the cluster it monitors. Any clues are
welcome.
