Hello, Using Xymon 4.3.7 I see in my /var/log/xymon/xymonlaunch.log log file the following error: =================================== 2012-03-12 16:07:57 Loading tasklist configuration from /home/xymon/server/etc/tasks.cfg 2012-03-12 16:07:57 Cannot open directory =================================== This isn't too much use since it doesn't say what directory it is trying to open.

List of graphs of a devmon test is too long
by Wim.Nelis＠nlr.nl 12 Mar '12

12 Mar '12

Hello, we are using xymon 4.3.7 and devmon 0.3.1-beta1, r233. Some of the devmon tests on interfaces of switches and routers use the rrd collector of xymon. Those tests contain thus both a table and additionally one graph per interface. However, for *each* test using the devmon rrd collector there are three additional pointers to non-existing graphs. The number of additional non-existing graphs is thus independent of the number of interfaces being monitored. The following is the page source of a test to check for packet drops on 3 interfaces of a router: <TR><TD ALIGN=LEFT><H3> Thu 2012.02.23 10:58:22</H3> <PRE> <b>Interface discards:</b> Input discard load alert thresholds: yellow=5.0%, red=10.0% Output discard load alert thresholds: yellow=5.0%, red=10.0% <table border=1 cellpadding=5> <tr><th>If name</th><th>Packet rate in</th> ... </tr> <tr><td>eth0</td><td>10.55</td> ... </tr> <tr><td>eth1</td><td>18.05</td> ... </tr> <tr><td>eth2</td><td>0.00</td> ... </tr> <tr><td>wlan0</td><td>4.37</td> ... </tr> </table>  Note: Discard rate: Number of discards per second Discard load: Number of discards per packet Devmon version 0.3.1-beta1-r233 running on sodn164u </PRE> </TD></TR></TABLE> <br><br> <table align="center" border=0 summary="Status report info"> <tr><td align="center"><font COLOR="#87a9e5" SIZE="-1">Status unchanged in 6 days,21 hours, 2 minutes<br> Status message received from 137.17.28.26<br> </font></td></tr> </table>  <table summary="devmon:if_dsc Graph"><tr><td><A HREF="/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=1&count=1 ... <view-source:http://xymon.nlr.nl/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=1&count=1&disp=AChinook%2dnet&nostale&color=green&graph_start=1329818379&graph_end=1329991179&action=menu></table> <table summary="devmon:if_dsc Graph"><tr><td><A HREF="/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=2&count=1 ... <view-source:http://xymon.nlr.nl/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=2&count=1&disp=AChinook%2dnet&nostale&color=green&graph_start=1329818379&graph_end=1329991179&action=menu></table> <table summary="devmon:if_dsc Graph"><tr><td><A HREF="/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=3&count=1 ... </table> <view-source:http://xymon.nlr.nl/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=3&count=1&disp=AChinook%2dnet&nostale&color=green&graph_start=1329818379&graph_end=1329991179&action=menu> <table summary="devmon:if_dsc Graph"><tr><td><A HREF="/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=4&count=1 ... <view-source:http://xymon.nlr.nl/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=4&count=1&disp=AChinook%2dnet&nostale&color=green&graph_start=1329818379&graph_end=1329991179&action=menu></table> <table summary="devmon:if_dsc Graph"><tr><td><A HREF="/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=5&count=1 ... <view-source:http://xymon.nlr.nl/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=5&count=1&disp=AChinook%2dnet&nostale&color=green&graph_start=1329818379&graph_end=1329991179&action=menu></table> <table summary="devmon:if_dsc Graph"><tr><td><A HREF="/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=6&count=1 ... </table> <view-source:http://xymon.nlr.nl/xymon-cgi/showgraph.sh?host=nlrcve02-lan&service=devmon:if_dsc&graph_width=576&graph_height=120&first=6&count=1&disp=AChinook%2dnet&nostale&color=green&graph_start=1329818379&graph_end=1329991179&action=menu> The (very) long lines have been truncated, at the "...", to enhance the readability. In subdirectory ~xymon/data/rrd/nlrcve02-lan there are 3 RRDs, not 6. How xymon does determine the linecount, 6 in the example above, is not clear to me. However, it is the number of lines in the HTML comment section containing the RRD data, which is always 3 more than the number of interfaces. How can I configure xymon in such a way that the number of graphs matches the number of interfaces?

Patch to correct status unchanged time formatting
by john.horne＠plymouth.ac.uk 12 Mar '12

12 Mar '12

[Lifted from SF tracker #3498715] Attached is a trivial patch for the 'Status unchanged in' line displayed on the web page of individual services. The patch was produced against version 4.3.7 Xymon. Currently the 'status unchanged' line shows times like: Status unchanged in 1 days,0 hours, 11 minutes The patch puts a space after the first comma (,). It then only puts an 's' on the time if it is not '1'. So, the above becomes: Status unchanged in 1 day, 0 hours, 11 minutes (The patch is a little messy - using specific variables for the maths would be better.)

useradm.c - possible bug
by john.horne＠plymouth.ac.uk 12 Mar '12

12 Mar '12

Hello, In Xymon 4.3.7 the useradm.c file around line 126 shows: ================================ cmd = (char *)malloc(1024 + strlen(passfile) + strlen(adduser_name) + strlen(adduser_password)); sprintf(cmd, "htpasswd -b '%s' '%s' '%s'", passfile, adduser_name, adduser_password); n = system(cmd); n = system(cmd); ret = WEXITSTATUS(n); ================================ Just wondering why 'n = system(cmd)' is run twice?

Reporting bugs?
by john.horne＠plymouth.ac.uk 12 Mar '12

12 Mar '12

Hi, Just wondering where is the best place to report possible bugs? The sourceforge site says it is on this mailing list (http://sourceforge.net/projects/xymon/support) The SF tracker shows what seems like a lot of open bugs - 43 out of 46 in total open, 35 open feature requests out of 39 in total, 12 open patches against 13 in total, etc. Is tracker not really used then for Xymon?

How to setup a custom script to attempt server logons and other functions
by bewhite＠fellowes.com 11 Mar '12

11 Mar '12

The built in network ftp test. It will not check ids/passwords, but it does check that ftp is running and is accepting commands. It opens the 21 port on an ftp sever and then issues a quit to disconnect. All you need to do is put the "ftp" tag on the server's entry in the hosts.cfg file and Xymon will do the rest. If ftp is not functional, it will let you know. No need to write a script, no need to create a special ID for your script and no need to embed the password for you special user into a script. ......Bruce From: xymon-bounces at xymon.com [mailto:xymon-bounces at xymon.com] On Behalf Of Don Kuhlman Sent: Friday, March 09, 2012 11:13 AM To: xymon at xymon.com Subject: Re: [Xymon] How to setup a custom script to attempt server logons and other functions Thanks everyone for the quick and helpful replies!

Antw.: Extra column containing an access protocol (putty, telnet, mstsc)

To start something like Putty you would need to define a "helper app" on your computer. Telnet is already defined on Windows, but SSH is not.
