Hi all,
im trying to monitor my PC without NSClient++, instead i have enable and configure the SNMP service that windows have and uses as client. Control panel > administrative tools > Services and here in SNMP service you can configure the community string and on what host should send the SNMP info .... and im trying the simple check_nt check to see is it work and it show me this errors
root@nagios:/usr/local/nagios/libexec# ./check_nt -H 172.25.1.101 -p 162 -s MyPC -v UPTIME
Connection refused
could not fetch information from server
root@nagios:/usr/local/nagios/libexec#
so is there a way to get this work or do i have to install some client ... i canot see way this wont work or do i missing something ? I dont want to install the client or some kind of agent on some PC and servers and they are all windows and we have some policy for installing ... etc ..... any solution ?

Hi MPIvan,
As far as I know, check_nt requires NSClient to be installed.
SNMP monitoring should have it's own plugins which monitor required parts of a windows system (e.g. check_snmp).
Kind Regards,

MPIvan,
If you're looking to monitor windows without installing a client, I would recommend WMI over SNMP. Check_nt does require client software to be installed.

Tnx for reply ...
here is what iv got for now .... i was trying the check_snmp to see what will do, and it gave me the results ... as the solution of my question ... i guess it works ok but now i have problem loading or reading the mibs of my pc .... as you can see i have errors of missing mibs and i have to find the numbers or something instead of writhing the mibs name "sysUptime" i have to write the number and that is irritating .... any solution about this problem ??? how to download the mibs so i dont have to write the number i already do this for my Cisco Routers folowing this commands
Code: Select all
cd /usr/share/mibs/netsnmp
wget ftp://cisco.com/pub/mibs/v2/SNMPv2-MIB.my
wget ftp://cisco.com/pub/mibs/v1/RFC1213-MIB.my

wget ftp://cisco.com/pub/mibs/v2/SNMPv2-TC.my
wget ftp://cisco.com/pub/mibs/v2/SNMPv2-SMI.my
echo "mibs +sysUpTime" >> /etc/snmp/snmp.conf
but for windows i dont know how to do that and where to put them ...

Most mibs for windows devices are stored in c:\windows\system32\. I am not sure if sysuptime is available as you are expecting via MS mibs. As yancy mentioned, WMI is significantly easier to use and more powerful than snmp for windows machines. Such limitations as not even seeing an oid tree for services that are not running is one of the issues to getting reliable data on windows machines via snmp.

with this command iv got the result ...
Code: Select all
./check_snmp -H 172.25.1.101 -C MyPC -p 161 -o 1.3.6.1.2.1.1.3.0
but i want instead of oid ( the number ) to set/call with the name example: "sysUptime" MIB. Now i will try with WMI to see what can i get from there ....
and for MIB's that are missing i dont know how to import them in the Linux machine or Nagios server how to download or get or something so i dont get this error is there some automatic download procedure or do i have to download them manual. If i have to do this manual how and where to put them in Linux or Nagios in what directory ?

Each distro may handle mibs differently. What linux distro and version are you running on your core server?

It is Ubuntu server 12.04.2 LTS. And nagios is Nagios Core Version 3.4.1

Considering you are using check_snmp which uses net::snmp from perl I would look at this article:
