Formatting errors on log files
I haven't noticed any errors through xymond_client or from debug mode.
After running the xymoncmd line above I get the following:
./xymoncmd xymon 127.0.0.1 "xymondlog wstc-lr0dhcp1.svcs"

It appears to be when it is displayed on the webpage where the problem occurs. I have not updated xymon- it appears as though the version that I am on is still the most recent version (4.3.27) Is anyone aware of any conflicts that may have been introduced after patching? Since this is a production server, I run patches on a monthly basis, with the most recent patching occurring on 9/29, which is coincidentally when the problem started occurring.Can you run from the command line: xymoncmd xymon 127.0.0.1 "xymondlog <hostname>.<affectedtestname>" for a test (like svcs) that you're seeing now? I'm curious if the garbled data is showing in memory or if it's happening (just) on the web layer. I'm not aware of any outstanding issues in xymond_client code that wouldn't be affecting lots of people, but it's possible we have a bug here. Most of the recent changes have been either new features or CSP/XSS fixes at the display layer. Have you noticed any errors coming through xymond_client, or any patterns from running it in --debug mode? -jcOn Mon, Oct 17, 2016 at 4:27 PM, Greg Krpan <user-aaa61fac9dfe@xymon.invalid> wrote:I've included an entire "SVCS" status below on a failed status screen.

Does the data after the corrupted lines appear to match the remaining data for the server in question? From the sample below it seems not (as I believe this is reported in alphabetical order), which might indicate indicate a broader memory corruption issue going on within xymond_client, where it's somehow losing track of the end or garbling the data in the buffer being used for holding status output. If it's causing a false positive, then it's not merely the final output that's the problem, but something occurring earlier in processing. What OS+distro is the server running on? Any chance you might be able to run xymond_client in debug mode for a bit while this is occurring? -jc On 10/17/2016 7:56 AM, Greg Krpan wrote: Hi JC- Thanks for the response. I am using Xymon 4.3.27 currently. The raw client data looks fine- there are no corrupted lines and no added brackets or special characters that I can see. This only occurs on the status pages. The server has been running since May, and this particular problem started at the end of Sept., after running Windows Update on my servers, but as both Windows and Linux clients are showing the behavior, I have ruled out the updates as the issue. I have tried restarting the service with no effect on behavior and there is nothing in the log files that show a problem that I can see. The level of false positives due to formatting errors has remained relatively consistent, and tends to be limited to the PROCS (Win, Linux) and SVCS (Win only) tests, but occasionally will see the same error occurring on the DISK and CPU tests, although that is significantly less frequent, and is not across all configured machines. The PROCS/SVCS tests are showing random errors on one machine or another approximately every 5 minutes. Thanks Greg. On Fri, Oct 14, 2016 at 6:52 PM, J.C.

There's a known issue in that lines starting with a bracket will cause missing data, and this can happen more frequently on Windows servers just by virtue of some of the data that's coming across, but that doesn't appear to be causing this specific issue. Can you confirm which version of Xymon server you're using? Do you see the same corruption in the "raw" Client Data for the affected servers, or is it only occurring on the status pages? Also -- anything unusual in the log files? Has this problem been constant since it started, or is it getting worse? Does restarting the xymon service fix it (temporarily)?
