convert to FQDN
by jdustin＠usm.maine.edu 28 May '14

28 May '14

Greetings - I've been using Xymon (and Hobbit, and Big Brother before that) for many years. And unfortunately a decision I made LONG AGO is now rearing its ugly head: Fully Qualified Domain Names. Long ago I decided to use short names, and for the most part this has worked well. But now I need to convert to FQDN, and want to make certain I know all the steps involved: - edit hosts.cfg, perhaps use the CLIENT tag until I have all clients use FQDN - edit analysis.cfg, also changing hostnames - ditto for alerts.cfg - edit xymonserver.cfg, change FQDN to TRUE All the above is relatively straightforward. But something is reminding me about all the RRD files I have for my hosts. Do I need to rename them as well? Or will a "xymon 0 'rename SHORTNAME HOSTNAME.corp.org' " take care of this? And is there a way to have Xymon running to receive all the RENAME messages, yet disable network tests so new "phantom" hosts are not created? Thanks for reading and passing along any suggestions you may have. -- Jon Dustin - Network Specialist University of Southern Maine Portland, ME 207-780-4152

[PATCH] configure: error on unknown arg
by kdreyer＠usgs.gov 28 May '14

how to upgrade
by kspringer＠innovateteam.com 27 May '14

27 May '14

Maybe I'm missing something but I can't seem to find any info on how to actually perform an upgrade on the xymon server. I'm using v4.3.12 and would like to use the latest version so I can have more customization on the info and trends icons. I've never actually done an upgrade before, just fresh builds. What are the steps? Thank you. ------------------------------------------------ Kris Springer

Column order and accessibility of the 'info' column
by john.thurston＠alaska.gov 27 May '14

27 May '14

We're finding the 'info' column to be very important to us, but are also finding it a little difficult to find in the web displays. Since the number and titles of the columns displayed for each group vary, it is impossible to know which green diamond is the 'info' column without consulting the group-header. Is is difficult in a couple of cases: + If there are many hosts in a group, it can be hard to do the row/column matching to click the correct 'info' button. + If we use the 'find host/jump' function, the found host is at the top of the page and we must scroll up to find the header. I can think of several ways to make this more usable: + Use a unique icon (or icon set) for 'info'. Is 'info' ever be anything but green? + Let me rename the 'info' column like we can the 'conn' column. If it were named ' info' it would always sort to the left. + Let me specify an alternative column sort order for my pageset. + Make the 'find/jump' option jump to the group rather than the host. Can anyone suggest another way (which is already possible) I can use to improve the accessibility of the 'info' column? -- Do things because you should, not just because you can.

Potential bug in FILE analysis
by everett.vernon＠gmail.com 27 May '14

27 May '14

Hi all Not sure if this really classifies as a bug or not. I am inclined to think it is. In clientlocal.cfg, I have [sunos] file:`/usr/bin/sudo /usr/bin/find /var/crash/ -type f 2> /dev/null` And this finds 2 files. /var/crash/bounds /var/crash/vmdump.0 So far so good. However, /var/crash/ is a symlink to /var/share/crash/ And /var/share/crash has permissions or 700 So Xymon can determine there is a file, but cannot collect any metadata on the file, since it cannot stat the files in /var/share/crash/ In analysis.cfg I have this line (with appropriate HOST= value, of course) FILE %^/var/cores/.* NOEXIST red When I go to the "files" page, I see the file names there. Clicking on the file names, I get this info. [file:/var/crash/vmdump.0] ERROR: Permission denied But no red status appears on the test. Testing, using a similar directory structure, where Xymon can stat the files, does give a red status. I can understand that Xymon can't give any info on the file because of permissions, but in this case, all I care about is that the file exists, which Xymon has determined. That should trigger a red status. Using Xymon 4.3.10 Regards Vernon -- "Accept the challenges so that you can feel the exhilaration of victory" - General George Patton

Potential bug in FILE analysis

To read the /var/core directory I added the xymon group to the root group on some machines, on others I have changed the perms. You have to change the perms to read the /var/crash/[hostname] directory though as it is 700 Regards, Nick Pettefar >>> Anybody know of a way to give Xymon elevated access permissions when it >>> stats files it's checking? >>> I would prefer not to change the directory permissions if I can avoid it. >>> >>> Thanks >>> Vernon

Removing a column from nongreen.html
by feld＠feld.me 23 May '14

23 May '14

Hello, I'm looking to remove a particular column from our nongreen.html view and I'm not sure how to accomplish this. Is there some setting I cannot locate that lets me add --ignorecolumns= to the XYMONGENOPTS specifically for the nongreen view? Also, any tips on creating a custom page with only the specific columns I want to view? Thanks, Mark

Monitoring Wifi connections
by maria.thors＠or.is 23 May '14

23 May '14

Hi, can anybody help me? I have created a script for xymon to monitor how many gadgets connect to our Sisco Wifi routers, both per router and per Ssid. I use snmp with this OID: "1.3.6.1.4.1.14179.2.1.1.1.38" to find the number on each of the Ssid:s and add them up. I use these OID:s: "1.3.6.1.4.1.14179.2.2.13.1.4.$ID.0" and "1.3.6.1.4.1.14179.2.2.13.1.4.$ID.1" to find the number of gadgets connected to the router with "$ID". Then I add them all up. The two sums are widely different where the Ssid sum is from 10 to 30 fewer. What am I doing wrong? Should the sums not show the same number of connections? Thanks Maria

Hi Vernon Apologies about the delayed reply. I ended up writing a script to achieve what I needed but thanks for the input anyway.

devmon template for Cisco ASR1000
by Paul.Root＠centurylink.com 21 May '14

21 May '14

Anybody have a template for these? I have the basics working, but I'm trying to get clustering working. I'm thinking the HSRP isn't configured correctly on our routers, but my network person thinks they are. If they are then snmp for it is useless. Also, I don't have power or fans either.
