Raspberry Pi Xymon Server (Mac OS X Macport Xymon client)

However I then used Macport to install the dependencies seperately and then I could carry on with the Xymon installation. Silly. (I change df -k to df -h to get a clearer display of disk statistics on every Xymon client I am responsible for.)

Raspberry Pi Xymon Server
by Nick＠Pettefar.com 08 Feb '13

08 Feb '13

Hi, I forgot to mention in my last posts that my Xymon server is a Raspberry Pi (512Mb, 950MHz clock) running Debian Squeeze and using a 32GB SD card for the main disk. The server is currently monitoring a Sun T2000 Solaris 10 box and an Apple Mac Mini as well as itself. (It is using minimal CPU.) I compiled the latest Xymon on the Pi. I used Mac Ports to make an Xymon client for the Mac Mini (OSX Mountain Lion) - you have to fiddle with the df command to get the right disk data, apparently it uses the new Unix standard byt Xymon doesn't. xymon at cream:~$ uname -a Linux cream 3.2.27+ #250 PREEMPT Thu Oct 18 19:03:02 BST 2012 armv6l GNU/Linux Xymon Version 4.3.10: 3 Aug 2012 World viewable at: http://ssh.pettefar.de:1984/xymon/ Regards, Nick Pettefar Dublin

Proxy Priority?
by sean.clark＠twcable.com 07 Feb '13

07 Feb '13

I have a setup like this: +------------------------+ +----------------------+ | xymon:1985 | | | |------------------------| | Downstream client | | xymonproxy:1984 | <-----+| | +------------------------+ +----------------------+ + | | | +-----> proxy sends to localhost:1985, and upstream host1 1984, upstream host2 1984 [this is repeated across several sites] The issue is, when downstream client looks to get it's config – in some sites, it gets the local-client from xymon:1985 host, but in others, it gets it from upstream hostX:1984 The xymondproxy in the tasks.cfg is identical in each place (--server localhost:1985, host1:1984, host2:1984) -- so I am confused as to why some get localhost, and some do not — the local-client is different in each place – and I'D prefer some setting I am missing (?) so that it always gets the local-client from the xymon:1985 instance. ________________________________ This E-mail and any of its attachments may contain Time Warner Cable proprietary information, which is privileged, confidential, or subject to copyright belonging to Time Warner Cable.

Xymon client on private network - proxy solution?
by denicoloj＠gmail.com 07 Feb '13

07 Feb '13

Xymon users & admins, I have a few servers(LDAP, QNAP/NFS, etc..) that are located on a private network but can be reached via ssh by tunneling through various other servers which are connected to the internet. I need to figure out how to have these private network clients send xymon reports to my xymon server located on the outside. I will try and map out the situation so you guys can have a better visual idea with fictional IPs. 2 Main subnets are controlled by me 120.15.130.x 120.15.131.x Server A : Main XYMON Server - 120.15.131.1 Server B : Current working Xymon Client - 120.15.131.2 & 192.168.1.2 (2nd NIC connected to a switch which is not connected to any other outside network) Server C : NFS Server - 192.168.1.3 - I need an xymon client installed on here and to be able to communicate(push reports) to the main xymon server by going through Server B(proxy). As you can see the NFS server is not accessible from the main two subnets (120.15.130/131), only accessible from a server connected to the switch. Connecting the xymon server to the private switch is not an option. Is there anyway I can have Server B proxy the report from Server C to Server A. Server B is already running tinyproxy, can I use this or do I have to use a special xymonproxy extension? I would like to avoid having a 2nd full xymon server, I would just like one of my current xymon clients to act as a proxy or relay server. Appreciate any help.

rdp unexpected response
by dhaycurrie＠leisurefitness.com 06 Feb '13

06 Feb '13

I had to rebuild my xymon server. I had it running well for years, but it needed a nice upgrade and I did this a couple of months ago. However a lot of the custom configuration I don't remember and I can't find in google. A lot of my rdp checks are getting Unexpected service response. I think most likely is because they have NLA (Network Level Authentication) selected. Is there a way to check without changing that setting? Most of my servers do not require access to other users so I don't want to lower the setting. Maybe the setting needs to be updated?

Alternative to conn test - check for any incoming data from client?
by jhillen＠draads.nl 06 Feb '13

06 Feb '13

Hi there, Quite a few of the clients I've setup to be monitored, are behind a firewall which does not allow a response to ping. As such, I can not use the conn test, a function which I do believe is rather important. As an alternative, I would like to have a (possibly periodic) check, to see whether any data is incoming from these clients, as an alternative to the connection test.. afterall, incoming data = working connection, at least between the client at the Xymon server. Might any one have any recommendations or perhaps a sample on how to accomplish such a feat? Kind regards, Joost Hillen. System Administrator Draads bv.

TS - hobbitd_client RED
by d.tom.schmitt＠L-3com.com 06 Feb '13

06 Feb '13

I am continuing to have a problem on my production system: CentOS with Xymon 4.3.0-0.beta2 I am getting the hobbitd_client ICON and the message says: - Program crashed - Fatal signal caught! Does anyone have an idea where to look to correct this problem? I cannot find anything in the 'Client data' link. I have 2 servers: monitorp and monitor2. Monitor2 watches monitor2 and begins alerting if monitorp does not answer a ping. I also did the following thinking that I might have a corrupted client program. - I copies the /home/xymon/client/bin directory from monitor2 -> monitorp - I restarted the client on monitorp - Still have the same problem You cannot DISABLE the ICON. You can drop the ICON but it comes right back from the client on the primary Xymon server. Thanks, Tom Schmitt Senior IT Staff - R&D L-3 Communication Systems West 640 North 2200 West P.O.
