!Using cacti to graph Exim+ClamAV statistics |

NB: This works for me. YMMV. |

Use the following PHP script (named script.sh) to get the info outta your logs: |

1. Create the cacti Data Input Method. Use a Script/Command Input Type, and provide the link to the script, ie /var/www/cacti/scripts/mailget.sh. Add in Output fields, such as 'notspam', 'total', 'malware', 'rbl', 'sa_spam', and 'spf'. |

2. Create a Data Source. Use a 3600 step (hourly stats) and select the Data Input method which you just created. You won't need to specify a data source path as cacti inserts this automatically. After creating the initial source, create Data Source Items for each field. Use a GAUGE Source Type (I had used ABSOLUTE initially but this really wasn't working - most because I didn't read the RRDTOOL documentation properly (especially http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/tutorial/rrdbeginners.html). Use a 7200 Heartbeat. Insert a sane maximum value for each field according to how many rbl bounces/spam messages you foresee receiving each hour. |

I seemed to have problems if I didn't enter all the details for the data source within 5 minutes (after you add a new Data Source cacti creates the RRA for it each 5 minute cron run). If you find you're having problems with the newly created data source, try changing the filename cacti has automatically created (for example, if it's <path_rra>/spam_1.rrd try <path_rra>/spam_2.rrd. cacti will re-create it on the next crontab run. |

Pick the associated Output field for each Data Source Item, and then click Save (you'll need to do this after adding each item). |

3. Click on Graph Management, then Add. It's all pretty self-explantory from here. Set the base value as 1000. Don't worry about setting upper or lower limits, as you'll probably want to use auto-scale. After you've created the initial graph, add in Graph Items for each series you wish to graph, picking the appropriate Data Source. |
