Diagnostics Gatherer for Ubuntu Server
This repository is superseded by the lnxdiagd repository
This repository provides a number of python-based daemons that gather various system diagnostics. Although specifically targeted at my own Ubuntu Server (15.04), most will probably work (with minor modifications) on any Debian-based installation and probably also on other Linux systems.
The result of each daemon is a file containing comma-separated-values created in /tmp/ubundiagd/
The code used to daemonise python code was borrowed from previous work by:
- Sander Marechal (see: http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/)
- Charles Menguy (see: http://stackoverflow.com/questions/10217067/implementing-a-full-python-unix-style-daemon-process)
and modified for my particular use-case. This includes a bash-script that keeps the daemons running.
NO code is provided for further processing of the data. E.g. adding the data to a rrdtool-database and/or graphing the data. This functionality is offered elsewhere.
Following daemons are provided:
- daemon11 - CPU and motherboard temperature in degC (requires
lm-sensors) - daemon12 - CPU load (from
/proc/loadavgandvmstat) - daemon13 - Network interfaces (bytes in/out from
/proc/net/dev) - daemon14 - Memory usage (from
/proc/meminfo) - daemon15 - Size of logfiles (
kern.log,smartd.logandsyslog.log) - daemon19 - Temperature of the disk-array in degC (requires
smartmontools) - daemon21 - Ambient temperature as supplied by the TEMPer USB device. (requires
temperv14; source supplied with this repository) - daemon97 - Push data to MySQL-server
- daemon98 - Upload data to the server
- daemon99 - XML-file creation
The file config.ini contains the settings for each daemon. The following settings are provided:
- reporttime: Every seconds the daemon stores a result in the .
- cycles: Measurement data (samples) are kept and averaged across number of reports. This setting-name is a bit of a misnomer. It will be renamed at a later time.
- samplespercycle: The number of samples per cycle.
- lockfile: The name of the file used for locking the resultfile.
- resultfile: The name of the file used by daemon97.
- rawfile: The name of the CSV-file used by daemon98.
- sqlcmd: The MySQL command used to add the data to the database.
