- watching multiple logfiles at once
* Collecting system data with 'nmon'
- things learned from wrapping 'nmon'
* Safely using 'ssh'
- 'authorized_hosts'
* Connecting to multiple sites via 'ssh'
- collecting information from several remote systems at once
* Pushing code and modules to remote sites
- running perl scripts on other systems without installing them (or the modules they need) there
* Collecting data: data formats to use
* Storing data into RRDs (Round-Robin-Databases)
- using the 'RRDp' module
* Creating graphs from RRDs manually
* Creating graphs with 'drraw'
