Hi all, I've been using MRTG to graph our Nokia IPSO appliances, and all is well for most of the oids. Since I've switched to RRD and 14all.cgi, one oid in particular keeps failing.
Environment: Redhat 9.0 with patches MRTG 2.10.5 PERL 5.8.0 RRD 1.0.42 14all.cgi 0.3 I don't know if the problem is in mrtg, rrd, or 14all.cgi. Here's what I see in my Apache log file: [Tue Dec 23 10:21:48 2003] [error] [client x.x.x.x] Use of uninitialized value in abs at /var/www/mrtg/cgi-bin/14all.cgi line 242., referer: http://foo.foo.com/comm-1.html [Tue Dec 23 10:21:48 2003] [error] [client x.x.x.x] Use of uninitialized value in abs at /var/www/mrtg/cgi-bin/14all.cgi line 242., referer: http://foo.foo.com/comm-11.html [Tue Dec 23 10:21:48 2003] [error] [client x.x.x.x] Illegal modulus zero at /var/www/mrtg/cgi-bin/14all.cgi line 242., referer: http://foo.foo.com/comm-1.html [Tue Dec 23 10:21:48 2003] [error] [client x.x.x.x] Premature end of script headers: Other identical boxes can run this oid, and work fine with mrtg, rrd, 14allcgi. Here's a net-snmp query for the CPU oid: [EMAIL PROTECTED] apps]$ ./snmpget -cfoo x.x.x.x 1.3.6.1.2.1.25.3.3.1.2.1 SNMPv2-SMI::mib-2.25.3.3.1.2.1 = INTEGER: 44 and here is the base RRD "fetch" [EMAIL PROTECTED] mrtg]$ /usr/sbin/rrdtool fetch x.x.x.x_9.rrd AVERAGE --start 1072184822 --end now ds0 ds1 1072184700: 2.7180000000e+01 1.0000000000e+02 1072185000: 2.6380000000e+01 1.0000000000e+02 1072185300: 2.7613333333e+01 1.0000000000e+02 1072185600: 2.8213333333e+01 1.0000000000e+02 1072185900: 3.1170000000e+01 1.0000000000e+02 1072186200: 4.1243333333e+01 1.0000000000e+02 So it looks like the net-snmp query for the OID is good, and the RRD is good. The html and cfg files are identical except for the IP addresses of the 2 boxes. How can debug this beast?
