[smokeping-users] ERROR: opening '/tmp/smokeping-ms/data/mysite1/myhost1.rrd': No such file or directory

Layla:

Sorry about that, was working with MRTG yesterday and use cronjobs in that all the time.  I misled you when I asked if you were using cronjobs and I apologize for that.

What I should have said is, did you make sure that you've started the SmokePing daemon and that you've given it enough time to create the data?  It can take upwards of 15 mins or so to start generating the data.

Josh -

thank you very much for your response.

I have yet to do anything with crontab on this system.   I was going
to follow your suggestion, and I checked in the smokeping directory
but the only reference I find to cron seems to be for tSmoke, about
sending email updates on the system status.    Could you tell me what
you mean by the cron job?

Also I've been trying to figure out smokeping creates the initial rrd
file, but I'm still puzzled by this.  Could you tell me where I should
look to understand that better?

thanks again

LN
