Good Morning Gentlemen ?

I would like to take the Time to THANK All of you for your Excellent Assistance ! As this morning with your Feedbacks, we were able to Resolve our Buffer Issues :D We did so by Increasing 3 of the Parameters on our Xymon Server: MAXMSG_CLIENT MAXMSG_STATUS MAXMSG_DATA

Honestly I am extremely Impressed by the Excellence & Rapidity of your Replies :D As being a Freeware, I really wasn?t expecting much (reply wise) !

So KUDOS guys ! Your Help was Amazing :D Keep up your Excellent Work

CAUTION: This email originated from outside of the organization. Read more here: phishing.beaware.volvo.net<https://phishing.beaware.volvo.net/> I believe Malcolm is correct... Here is the section of the xymonserver.cfg file that deals with the buffer sizes :

Maximum message size buffers (in KB)

These are commented out by default, you should only change them if you

have systems sending large status-messages or otherwise need to handle

large messages. Please read the description in xymonserver.cfg(5) first.

#MAXMSG_CLIENT=512 # clientdata messages (default=512k) #MAXMSG_CLICHG=$MAXMSG_CLIENT # client change messages (default=MAXMSG_CLIENT) #MAXMSG_STATUS=256 # general "status" messages (default=256k) #MAXMSG_STACHG=$MAXMSG_STATUS # status change messages (default=MAXMSG_STATUS) #MAXMSG_PAGE=$MAXMSG_STATUS # page messages (default=MAXMSG_STATUS) #MAXMSG_ENADIS=32 # enable and disable control messages (default=32k) #MAXMSG_USER=128 # "user" messages (default=128k) #MAXMSG_DATA=256 # "data" messages, if enabled (default=256k) #MAXMSG_NOTES=256 # "notes" messages, if enabled (default=256k)

You may be hitting the MAXMSG_DATA limit of 256K ? try increasing it in xymonserver.cfg. I would have thought you?d have seen xymond go yellow as well and show ?Oversize? errors.

(2nd Sending as I had forgotten a Screenshoot for the Value I changed to 10000 in the Powershell File, so sorry about this)

Hello ?

Sorry to bother you ... But I was wondering if you could possibly Help us ... with a weird Issue we started having this Week () If so here it is: At some point for the past couple of night, we started receiving the following ALERT:

            &red XymonPSClient: No matching service - want started/automatic

But when I look on the Windows Server, under the (Windows mmc) Service window, it is shown as Started ? But Xymon doesn?t see it as such ? Now what is weird is that the ClientLog does list it, but under the SVCS button ? I don?t see all of the Services almost all but the last portion is missing (depending on how many there are ... the more there are I guess the more I would be missing) ? So I was thinking that it might be related to some sort of a VARIABLE Type or Buffer Size (Limitation) that is just not big enough ... but when I looked at the ?xymonclient.ps1?, there are way too many lines for me to understand all of it an try to figure out what I would need to change :$ Also I only fiddle a Little bit in PowerShell so my skills are at best at the Beginner Level ? Thus this is why I am taking a Chance sending you this Email

Here are a few Screenshot to try to show you the Issue and what I saw there leaning me towards the Incorrect Variable Type or Buffer Size
