Unfortunately, there are only six digits on our counter so it really shows 000007. Most likely you will start to use RRDtool to store and process data collected via SNMP. retrieve that data and create graphs in PNG format for display on a web browser.

These names can also be written down as numbers and are 1 3 6 1 2 1. Databases. First the counter wrap: In our car we notice that the counter shows 999987. RRDtool stores the data differently, it doesn't start the "weekly" archive where the "daily" archive stopped. RDR. The branches that we follow are named: iso, org, dod, internet, mgmt and mib-2. What makes it interesting is that you can have several different archives of the same data, all using different resolutions. The increase should be nearly as high as the maximum counter value for that to happen, so chances are you would have several other problems as well and this particular problem would not even be worth thinking about. The first step in making use of RRDTool is to configure Traffic Server, identifying the interfaces that are to be monitored. Assume you got the program.
