Wireless Access

Hey guys,

I did an airwave server migration today, and all seems to have gone well and it is now receiving data again, however graphing does not seem to be working, either system performance graphs. Is there something wrong here?

The only thing I have changed was the time in amp_install after the initial restoral was done.

System > Status shows all in green

Is there something I need to restart here?

Some investigate shows errors in /var/log/messages

Any suggestions?

Was the time before you made the time change in the future?  If so, then the RRDs already populated themselves with data up to that point in time.  This means that you won't see updates until that time is passed.  What is the time of the RRD files?  You would probably see files in the future listed in /var/airwave/rrd/rrd_check.

If you're not seeing anything in that file, you can initialize the check with:

# touch /tmp/base 

# perl -e 'utime time+600, time+600, "/tmp/base"' 
# /usr/bin/find /var/airwave/rrd -newer /tmp/base -type f > /var/airwave/rrd/rrd_check

If this was based off of a backup restored, you can do:

# amp_disable

# mv /var/airwave/rrd /tmp/old_rrd

Then restore just the RRD portion by extracting the /var/airwave/rrd directory from the backup file (tar -xvf nightly_data.tar.gz /var/airwave/rrd), wherever you restore the RRD files, you can just move into /var/airwave/rrd.

If you don't happen to care about the past graph data, you can blow away the RRDs and recreate the base RRDs:

# amp_disable

# rm -rf /var/airwave/rrd

# cd /root/svn/mercury

# make

# amp_enable
