Use the script below for Mysql:   #!/bin/bash SQL_USERNAME=radius_username SQL_DATABASE=radius SQL_PASSWORD=your_password SQL_SERVER=127.0.0.1 SQL_ACCOUNTING_TABLE=radacct BACK_DAYS=5 SESSIONS=`mysql -BN -u$SQL_USERNAME -p$SQL_PASSWORD -h $SQL_SERVER $SQL_DATABASE -e \ “SELECT COUNT(*) FROM $SQL_ACCOUNTING_TABLE \ WHERE acctstoptime IS […]

MRTG needs at least 2 values to generate graphs. Thus, Most configurations contain the same OID twice in the target line. This leads to 2 problems: – The same data is collected twice which requires more bandwidth, especially when a large number of hosts is monitored – The value may vary during this very short […]
