Hello, Xymon 4.3.7 xymonnet.c has the following line (line 491): * - '|' denotes reverse test, i.e. service should be DOWN. Surely the '|' should be a '!' character. John. -- John Horne Tel: +44 (0)1752 587287 Plymouth University, UK Fax: +44 (0)1752 587001

Hi again, I found a Xymon config file which seems to hold the default setup for the RRD graphs created within Xymon (rrddefinitions.cfg). The contents look like this: # 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg. RRA:AVERAGE:0.5:1:576 # 576 datapoints w/ 6*5 minute averaged = 12 days @ 30 min avg. RRA:AVERAGE:0.5:6:576 # 576 datapoints w/ 24*5 minute averaged = 48 days @ 2 hour avg. RRA:AVERAGE:0.5:24:576 # 576 datapoints w/ 288*5 minute averaged = 576 days @ 1 day avg. RRA:AVERAGE:0.5:288:576 Would I be correct saying that if I *add / append* the following lines, this would include the LAST value to all new graphs created still keepign the AVERAGE? # 576 datapoints w/ 5 minute interval = 48 hours @ 5 min avg. RRA:LAST:0.5:1:576 # 576 datapoints w/ 6*5 minute averaged = 12 days @ 30 min avg. RRA:LAST:0.5:6:576 # 576 datapoints w/ 24*5 minute averaged = 48 days @ 2 hour avg. RRA: LAST:0.5:24:576 # 576 datapoints w/ 288*5 minute averaged = 576 days @ 1 day avg. RRA: LAST:0.5:288:576 Thanks, James > Message: 1 > Date: Fri, 30 Mar 2012 12:21:38 +0200 > From: James McDonald <j.mcdo73 at gmail.com> > To: xymon at xymon.com > Subject: [Xymon] Change default RRD graph definitions > Message-ID: > <CAE4zdC1WB8F+zyTFjTRX2bO8aV8K6ON3UkMbwL2Xt2-=PqgSyg at mail.gmail.com > > > Content-Type: text/plain; charset="iso-8859-1" > > Hello, > > I'm looking to change the graph definitions for one of the built-in checks > e.g. [http]. > > The default creation method for the RRD graphs is "average", but I want to > display the "last" value instead.

IPv6 support in xymon
by John.Gibbins＠csiro.au 01 Apr '12

Thanks Henrik, That is good to hear. We did find that fping on SuSE Linux Enterprise was an ancient one that did not support IPv6. Even on SLES 11 SP2 it is still fping-2.4b2-94.22. We downloaded and installed fping-2.4b2_to-ipv6 (which is over 10 years old!) in order to support IPv6. I don't know what other distributions provide. Great work. I look forward to the upcoming release. regards johng -- John Gibbins Team Leader - IT Security/Authentication (and IPv6 Evangelist) CSIRO Information Management & Technology (IM&T) Phone: +61 2 6124 1419 | Fax: +61 2 6124 1414 | Mob: 0419 605 562 John.Gibbins at csiro.au | www.csiro.au PO BOX 225, Dickson ACT 2602 The only way of discovering the limits of the possible is to venture a little way past them into the impossible. - Clarke's Second Law -----Original Message----- Date: Fri, 30 Mar 2012 23:20:53 +0200 From: Henrik St?rner <henrik at hswn.dk> To: xymon at xymon.com Subject: Re: [Xymon] IPv6 support in xymon Message-ID: <4F7623B5.70909 at hswn.dk> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 30-03-2012 11:05, John.Gibbins at csiro.au wrote: > We are deploying IPv6 across our organisation (spread across > Australia) and use xymon for a lot of our monitoring.

I'm > curious whether there is an estimate of when this might come out. It is actually fairly close. I have IPv6 working on the Xymon server main daemon (xymond), and the client-side tool (xymon) that communicates with xymond also supports it. So basic IPv6 support is working. Support in the xymonnet tool - that runs the network tests - is underway; it is taking longer than I first expected because I've ended up writing a completely new network test tool instead of hacking the old code. The original xymonnet tool was almost 10 years old, and I've learned a lot about C programming during that time. Also, I wanted to make network tests be analysed in a manner similar to client data - i.e. feed it all into the Xymon server, then have a tool analyse and correlate data centrally. This is currently at a point where the new "xymonnet2" tool can perform the network tests, also against IPv6 enabled hosts and send the data to Xymon, but I have only started doing the analysis module. "ping" tests also haven't been implemented yet, but that should be a very simple thing to do - it will rely on "fping" for both IPv4 and IPv6 hosts. I hope to have it finished for release in a few months.
