    Re: Event Histograms not showing any events

    Thank YOU, Matt... looks like my ugly script got a nice overhaul.

    Re: Event Histograms not showing any events

    I did something like this on my Zenoss system... but it is a nasty hack job.

     

    I setup a 'One Hour Top 10 List', and basically I am doing a query that dumps to a text file a list of the 10 devices with the most events in the past hour.  The text file is saved on my web server, then I display that on the dashboard with the 'Site Window' portlet.

    The Site Window portlet works with either solution.  If you have a performance graph (like the custom one described 2 posts up) or the one generated by this ZenPack, you can post it to your dashboard with the Site Window portlet (see the Fun with the Site Window Portlet wiki entry for instructions).  You can also have multiple Site Windows on your dashboard, so it's relatively easy to populate your dashboard with your important graphs.

    Re: Event Histograms not showing any events

    I found that the top event counts often obscure key single events, such as a fan failure or a DSP crash (both of which I've seen in the last month).  When I was told about a syslog summary script that summarized all events, it made it easy to not miss those key events.  The syslog summary script, with some supporting web scripts, are at http://www.netcraftsmen.net/resources/technical-articles/712-syslog-summary-scripts.html

    Re: Event Histograms not showing any events

    You can can do this with the multi-graph report tool.  Setup your graphs up to be area+stacked with all events on a single graph.

     

    The bummer is that RRD will, by default, append a legend line for every single device and severity event making for an absurd graph legend that is much larger than the graph itself.  I'm sure there is a way to prevent this, perhaps with customer graph definitions, but I haven't chased it down.  Setting the graph definition value 'Has Summary' to False helps, as does removing the 'Legend' values, but this only eliminates a portion of the clutter.  If someone else figures this out please share. 

     

    Update:  Using a custom graph definition that includes the '-g' option will omit all the legend text and produce a simple, clean graph.

    All you need is to put '-g' (no quotes) in that box.

    You can manually specify your own colors when you setup the graph points in the 'Color (Hex value RRGGBB) field'.

    I don't know how to change that, but would love to hear about it if you figure it out.
