Error Message when Viewing a Report
Problem
Apparent Error Message: viewing a report returns with an error message Error opening <RRD
archive name>.rrd: No such file or directory
.
Cause and Solution
MRTG did not create RRD DB files. Verify that your <RTM Folder>/sce_<SCE IP> does not
contain *.rrd files.
There are two possible reasons that MRTG did not create the RRD DB files:
1. MRTG execution failed and you should check the following settings are correct:
a) Verify the SCE is accessible, e.g. ping.
b) Verify the SCE SNMP agent is enabled.
c) Verify the SCE community string is configured correctly in the RTM user configuration
file.
d) Verify the RTM directory is configured correctly in the user configuration file. The path
cannot contain white space.
Note: Use slash or '\\' as the path delimiter.
e) Verify the RRDTool bin directory is configured correctly in the user configuration file.
Note: Use slash or '\\' as the path delimiter.
f) Run MRTG from a command prompt and verify that it completes with no errors:
perl <MRTG bin folder>/mrtg <RTM folder>/mrtg-cfg/<SCE
address>_scabb_mrtg.cfg
