After deleting this file, the selfmonitor should have started the SNMPd automatically, but please check if it is really running. Is the cron daemon running, too? Check /var/log/system.log : every 5 minutes, a line like " /USR/SBIN/CRON[19833]: (root) CMD ( /usr/local/bin/reportcontrol.sh)" should appear. Take a look at the reporting files in /var/log/reporting/rrd and /var/log/reporting/accu, too. Are they modified regularly? Are the file sizes OK (i.e. greater than 0)?
