I've had this problem, and it's often related to a Stale NFS mount or other reason snmp can't stat the filesystem. If it's a stale mount, and you can't umount it (often due to the remote nfs server being down, or no longer sharing its exports) try:<div> </div><div>mount -rf /<mounted_fs></div><div> </div><div>It may come back with an error, saying it's mounted it ro, and you may need to repeat this command several times, it MAY umount. There is a chance you'l have to bite the bullet and reboot.</div> <div> </div><div> <div class="gmail_quote">On Fri, Sep 10, 2010 at 7:36 AM, Dorfman, Justin <<a href="mailto:justin@mahalo.com">justin@mahalo.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Ananth,<div> </div><div>This is how we check an SNMP process (in commands.cfg):</div><div> </div><div><div class="im"><blockquote class="gmail_quote" style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0.8ex;border-left-width:1px;border-left-color:rgb(204, 204, 204);border-left-style:solid;padding-left:1ex"> # 'check_snmp' command definition </blockquote><blockquote class="gmail_quote" style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0.8ex;border-left-width:1px;border-left-color:rgb(204, 204, 204);border-left-style:solid;padding-left:1ex"> define command{</blockquote></div><blockquote class="gmail_quote" style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0.8ex;border-left-width:1px;border-left-color:rgb(204, 204, 204);border-left-style:solid;padding-left:1ex"> command_name check_snmp_process</blockquote><blockquote class="gmail_quote" style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0.8ex;border-left-width:1px;border-left-color:rgb(204, 204, 204);border-left-style:solid;padding-left:1ex"> command_line $USER1$/<a href="http://check_snmp_process.pl" target="_blank">check_snmp_process.pl</a> -H $HOSTADDRESS$ -C $USER3$</blockquote> <blockquote class="gmail_quote" style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0.8ex;border-left-width:1px;border-left-color:rgb(204, 204, 204);border-left-style:solid;padding-left:1ex"> }</blockquote></div><div> </div><div>I would recommend you downloading these perl scripts: <a href="http://nagios.manubulon.com/index_snmp.html" target="_blank">http://nagios.manubulon.com/index_snmp.html</a> and putting them into your /usr/local/nagios/libexec folder.</div> <div> </div><div>Let me know how it goes.</div> <div> </div><div><div class="im"> Regards, Justin Dorfman Mahalo.com Inc. > Jr. Systems Engineer 818.485.1458 <a href="http://www.twitter.com/jdorfman" target="_blank">@jdorfman</a> | <a href="http://twitter.com/MahaloSysops" target="_blank">@MahaloSysops</a> | Blog: <a href="http://bit.ly/aNiWSk" target="_blank">http://bit.ly/aNiWSk</a> </div><div><div></div><div class="h5"><div class="gmail_quote">On Thu, Sep 9, 2010 at 2:36 AM, IT Toonz <<a href="mailto:it.toonz@gmail.com" target="_blank">it.toonz@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div lang="EN-IN" link="blue" vlink="purple"> <div> Hi Justin, We have the native SNMP in Windows installed and we wanted to monitor those readings. We downloaded and installed Net-SNMP, but seems there a bit of configuring to do, we are fiddling with Nagios settings, so not sure whether we want to spend time learning Net-SNMP at present. But its definitely something which we want to look at in the future. Thanks for sharing the info. Meanwhile we are still stuck in SNMP!! This is what we get when we run [root@Nagios nagios]# snmpwalk -v1 -c taipl 192.168.3.100 snmp SNMPv2-MIB::snmpInPkts.0 = Counter32: 1 SNMPv2-MIB::snmpOutPkts.0 = Counter32: 11 SNMPv2-MIB::snmpInBadVersions.0 = Counter32: 0 SNMPv2-MIB::snmpInBadCommunityNames.0 = Counter32: 0 SNMPv2-MIB::snmpInBadCommunityUses.0 = Counter32: 0 SNMPv2-MIB::snmpInASNParseErrs.0 = Counter32: 0 SNMPv2-MIB::snmpInTooBigs.0 = Counter32: 0 SNMPv2-MIB::snmpInNoSuchNames.0 = Counter32: 0 SNMPv2-MIB::snmpInBadValues.0 = Counter32: 0 SNMPv2-MIB::snmpInReadOnlys.0 = Counter32: 0 SNMPv2-MIB::snmpInGenErrs.0 = Counter32: 0 SNMPv2-MIB::snmpInTotalReqVars.0 = Counter32: 11 SNMPv2-MIB::snmpInTotalSetVars.0 = Counter32: 0 SNMPv2-MIB::snmpInGetRequests.0 = Counter32: 0 SNMPv2-MIB::snmpInGetNexts.0 = Counter32: 14 SNMPv2-MIB::snmpInSetRequests.0 = Counter32: 0 SNMPv2-MIB::snmpInGetResponses.0 = Counter32: 0 SNMPv2-MIB::snmpInTraps.0 = Counter32: 0 SNMPv2-MIB::snmpOutTooBigs.0 = Counter32: 0 SNMPv2-MIB::snmpOutNoSuchNames.0 = Counter32: 0 SNMPv2-MIB::snmpOutBadValues.0 = Counter32: 0 SNMPv2-MIB::snmpOutGenErrs.0 = Counter32: 0 SNMPv2-MIB::snmpOutGetRequests.0 = Counter32: 0 SNMPv2-MIB::snmpOutGetNexts.0 = Counter32: 0 SNMPv2-MIB::snmpOutSetRequests.0 = Counter32: 0 SNMPv2-MIB::snmpOutGetResponses.0 = Counter32: 25 SNMPv2-MIB::snmpOutTraps.0 = Counter32: 10 SNMPv2-MIB::snmpEnableAuthenTraps.0 = INTEGER: enabled(1) So seems client side is fine.
