[mrtg] Re: problem about External Monitoring Scripts

[Grossman, Benjamin]

This sounds familiar. I suggest that you examine the access rights
(privileges) of your script, directories & the cron user in question.

Subject: [mrtg] problem about External Monitoring Scripts


hey, this time I applied an external monitoring script to monitor a single
value  that snmp can't provide directly. when I ran mrtg to generate the
data for the 
target log manully, it appeared very good, and I could browse the right
graph from IE with the right target name and system uptime. but when the
mrtg was 
automatically run by crontab, all data of target log turned 1 or -1, and
target name and system uptime of IE became unknown, the graph could tell
nothing but 
wrong data. when i manully ran the task of crontab, all things seemed ok
again. 
Could anybody tell me why it would be that? Is there anything I should be 
careful? Thanks a lot!
