SNMP Restart

When you get an error similar to Instance i-97a50fef (79.124.89.83) doesn't respond to SNMP. Scalr was able to open connection to UDP port 161, but snmp doesn't respond. Most likely snmpd is hung up. Try to restart it with /etc/init.d/snmpd restart.

This typically means that Scalr is unable to contact your server, because the communication protocol is blocked. Try checking your Security Groups / Firewall, if restarting the service does not work.
