Hi there Wonder if someone can explain this error for me.
I have written a perl script which updates the rrd files, but waits until it has 10 entries before it writes to the rrd file. Its generally working although occasionally I get the error RRDTool Update ERROR: reading the cookie off e:/snmp-poller/10.127.254.48/10.127.254.48-ifOutErrors_13.rrd faild Does this mean the perl script cannot get a lock on the file for some reason? Its not multi threaded so am scratching my head a bit as to understand why I would have file locking errors if this is indeed the reason Thanks Richard > -----Original Message----- > From: Richard Burton > Sent: 06 September 2006 16:42 > To: '[email protected]' > Subject: RE: [rrd-users] Re: Multi threaded Perl scripts using RRDTool > > Hi Tobi and Alex > > Thanks for the advice, I think I will go down the route of > running several updates to a single file and see how much I > can speed things up by.
