For exemple to set the refrech rate to 5 seconds: - - $ glances.py -t 5 - -Importants stats are colored: - -* GREEN: stat counter is "OK" -* BLUE: stat counter is "CAREFUL" -* MAGENTA: stat counter is "WARNING" -* RED: stat counter is "CRITICAL" - -When Glances is running, you can press: - -* 'h' to display an help message whith the keys you can press -* 'a' to set the automatic mode. The processes are sorted automatically - - If CPU > 70%, sort by process "CPU consumption" - - If MEM > 70%, sort by process "memory size" - -* 'c' to sort the processes list by CPU consumption -* 'd' Disable or enable the disk IO stats -* 'f' Disable or enable the file system stats -* 'm' to sort the processes list by process size -* 'n' Disable or enable the network interfaces stats -* 'q' Exit - -### Header - - - -The header shows the Glances version, the host name and the operating -system name, version and architecture. - -### CPU - - - -The CPU states are shown as a percentage and for the configured refresh -time. - -If user|kernel|nice CPU is < 50%, then status is set to "OK". - -If user|kernel|nice CPU is > 50%, then status is set to "CAREFUL". - -If user|kernel|nice CPU is > 70%, then status is set to "WARNING". - -If user|kernel|nice CPU is > 90%, then status is set to "CRITICAL". - -### Load - - - -On the Nosheep blog, Zach defines the average load: "In short it is the -average sum of the number of processes waiting in the run-queue plus the -number currently executing over 1, 5, and 15 minute time periods." - -Glances gets the number of CPU cores to adapt the alerts. With Glances, -alerts on average load are only set on 5 and 15 mins. - -If average load is < O.7*Core, then status is set to "OK". - -If average load is > O.7*Core, then status is set to "CAREFUL". - -If average load is > 1*Core, then status is set to "WARNING". - -If average load is > 5*Core, then status is set to "CRITICAL". - -### Memory - - - -Glances uses tree columns: memory (RAM), swap and "real". - -Real used memory is: used - cache. - -Real free memory is: free + cache. - -With Glances, alerts are only set for on used swap and real memory. - -If memory is < 50%, then status is set to "OK". - -If memory is > 50%, then status is set to "CAREFUL". - -If memory is > 70%, then status is set to "WARNING". - -If memory is > 90%, then status is set to "CRITICAL". - -### Network bit rate - - - -Glances display the network interface bit rate. The unit is adapted -dynamicaly (bits per second, Kbits per second, Mbits per second...). - -Alerts are set only if the network interface maximum speed is available. - -If bitrate is < 50%, then status is set to "OK". - -If bitrate is > 50%, then status is set to "CAREFUL". - -If bitrate is > 70%, then status is set to "WARNING". - -If bitrate is > 90%, then status is set to "CRITICAL". - -For exemple, on a 100 Mbps Ethernet interface, the warning status is set -if the bit rate is higher than 70 Mbps. - -### Disk I/O - - - -Glances display the disk I/O throughput. The unit is adapted dynamicaly -(bytes per second, Kbytes per second, Mbytes per second...). - -There is no alert on this information. - -### Filesystem - - - -Glances display the total and used filesytem disk space. The unit is -adapted dynamicaly (bytes per second, Kbytes per second, Mbytes per -second...). - -Alerts are set for used disk space: - -If disk used is < 50%, then status is set to "OK". - -If disk used is > 50%, then status is set to "CAREFUL". - -If disk used is > 70%, then status is set to "WARNING". - -If disk used is > 90%, then status is set to "CRITICAL". - -### Processes - - - -Glances displays a summary and a list of processes. - -By default (or if you hit the 'a' key) the process list is automaticaly -sorted by CPU of memory consumption. - -The number of processes in the list is adapted to the screen size. - -### Footer - - - -Glances displays a caption and the current time/date. - -## Localisation - -To generate french locale execute as root or sudo : -i18n_francais_generate.sh - -To generate spanish locale execute as root or sudo : -i18n_espanol_generate.sh - -## Todo - -You are welcome to contribute to this software. - -* Packaging for Debian, Ubuntu, BSD... -* Check the needed Python library in the configure.ac -* Add file system stats when the python-statgrab is corrected +README
