Thanks Jochen,

increasing the timeout to 30 seconds solved the problem. Now the System/Overview page displays correctly on the Graylog WebUI.

I will investigate if any particular errors appear on the server.log of the nodes when that page is requested (it currently takes some 10 seconds to load... I have no idea if this is a reasonable time, considering our setup).

Ciao
Lorenzo

Hi Lorenzo,

the error message you've seen ("[…] We expected HTTP 200, but got a HTTP -1.") is usually a sign of a request timeout. By default the request timeout for HTTP requests from the Graylog web interface to a Graylog server node is 5 seconds and can be customized in the configuration file of your Graylog web interface, see https://github.com/Graylog2/graylog2-web-interface/blob/1.2.0/misc/graylog-web-interface.conf.example#L31-L32 for details.

Of course it would also be interesting to find out why the request worked in the past and is running into a timeout right now. You should find some hints about this in your Graylog server node's log messages.


Cheers,
Jochen

    Hello everyone,

    i've been running Graylog (currently, version 1.1.6) on a three
    node cluster for several months, and recently (i suspect, from
    last week) the "System/Overview" page on the Web Interface has
    stopped running.

    The error is


          *Reason:* Could not fetch system information. We expected
          HTTP 200, but got a HTTP -1.


    And the stack trace is

    MongoDB runs as a replica set of 3 nodes, on the 3 servers which
    also run graylog-server and graylog-web.

    Apart from the unavailability of the system information,
    everything seems to be OK.

    I tried checking the configurationm files, and everything seems to
    be OK; i've just reinstalled graylog-server and graylog-web on all
    three nodes, but to no avail.

    Has everyone here experienced a similar problem?
    Could it be related with a corruption of the configuration data in
    Mongodb? Just an idea...

    The error appear on the web interface of all 3 nodes.

    Long live and prosper,

    Lorenzo
