9 glances [OPTIONS]
10
12 glances is a cross-platform curses-based monitoring tool which aims to
13 present a maximum of information in a minimum of space, ideally to fit
14 in a classical 80x24 terminal or higher to have additional information.
15 It can adapt dynamically the displayed information depending on the
16 terminal size. It can also work in client/server mode. Remote monitor‐
17 ing could be done via terminal or web interface.
18 glances is written in Python and uses the psutil library to get infor‐
20 mation from your system.

307
309 No configuration file is mandatory to use Glances.
310 Furthermore a configuration file is needed to access more settings.
312
314 NOTE:
315 A template is available in the /usr{,/local}/share/doc/glances
316 (Unix-like) directory or directly on GitHub.
317 You can put your own glances.conf file in the following locations:
319 ┌─────────────┬────────────────────────────┐
321 │Linux, SunOS │ ~/.config/glances, │
322 │ │ /etc/glances │
323 ├─────────────┼────────────────────────────┤
324 │*BSD │ ~/.config/glances, │
325 │ │ /usr/local/etc/glances │
326 ├─────────────┼────────────────────────────┤
327 │macOS │ ~/Library/Application Sup‐ │
328 │ │ port/glances, │
329 │ │ /usr/local/etc/glances │
330 ├─────────────┼────────────────────────────┤
331 │Windows │ %APPDATA%\glances │
332 └─────────────┴────────────────────────────┘
333 · On Windows XP, %APPDATA% is: C:\Documents and Settings\<USER‐
335 NAME>\Application Data.
336 · On Windows Vista and later: C:\Users\<USERNAME>\AppData\Roaming.
338 User-specific options override system-wide options and options given on
340 the command line override either.
341
343 Glances reads configuration files in the ini syntax.
344 A first section (called global) is available:
346 [global]
348 # Does Glances should check if a newer version is available on PyPI?
349 check_update=true
350 Each plugin, export module and application monitoring process (AMP) can
352 have a section. Below an example for the CPU plugin:
353 [cpu]
355 disable=False
356 user_careful=50
357 user_warning=70
358 user_critical=90
359 iowait_careful=50
360 iowait_warning=70
361 iowait_critical=90
362 system_careful=50
363 system_warning=70
364 system_critical=90
365 steal_careful=50
366 steal_warning=70
367 steal_critical=90
368 an InfluxDB export module:
370 [influxdb]
372 # Configuration for the --export influxdb option
373 # https://influxdb.com/
374 host=localhost
375 port=8086
376 user=root
377 password=root
378 db=glances
379 prefix=localhost
380 #tags=foo:bar,spam:eggs
381 or a Nginx AMP:
383 [amp_nginx]
385 # Nginx status page should be enable (https://easyengine.io/tutorials/nginx/status-page/)
386 enable=true
387 regex=\/usr\/sbin\/nginx
388 refresh=60
389 one_line=false
390 status_url=http://localhost/nginx_status
391 With Glances 3.0 or higher it is also possible to use dynamic configu‐
393 ration value using system command. For example, if you to set the pre‐
394 fix of an InfluxDB export to the current hostname, use:
395 [influxdb]
397 ...
398 prefix=`hostname`
399 Or if you want to add the Operating System name as a tag:
401 [influxdb]
403 ...
404 tags=system:`uname -a`
405
407 Glances logs all of its internal messages to a log file.
408 DEBUG messages can been logged using the -d option on the command line.
410 The location of the Glances depends of your operating system. You could
412 displayed the Glances log file full path using the``glances -V`` com‐
413 mand line.
414 The file is automatically rotate when the size is higher than 1 MB.
416 If you want to use another system path or change the log message, you
418 can use your own logger configuration. First of all, you have to create
419 a glances.json file with, for example, the following content (JSON for‐
420 mat):
421 {
423 "version": 1,
424 "disable_existing_loggers": "False",
425 "root": {
426 "level": "INFO",
427 "handlers": ["file", "console"]
428 },
429 "formatters": {
430 "standard": {
431 "format": "%(asctime)s -- %(levelname)s -- %(message)s"
432 },
433 "short": {
434 "format": "%(levelname)s: %(message)s"
435 },
436 "free": {
437 "format": "%(message)s"
438 }
439 },
440 "handlers": {
441 "file": {
442 "level": "DEBUG",
443 "class": "logging.handlers.RotatingFileHandler",
444 "formatter": "standard",
445 "filename": "/var/tmp/glances.log"
446 },
447 "console": {
448 "level": "CRITICAL",
449 "class": "logging.StreamHandler",
450 "formatter": "free"
451 }
452 },
453 "loggers": {
454 "debug": {
455 "handlers": ["file", "console"],
456 "level": "DEBUG"
457 },
458 "verbose": {
459 "handlers": ["file", "console"],
460 "level": "INFO"
461 },
462 "standard": {
463 "handlers": ["file"],
464 "level": "INFO"
465 },
466 "requests": {
467 "handlers": ["file", "console"],
468 "level": "ERROR"
469 },
470 "elasticsearch": {
471 "handlers": ["file", "console"],
472 "level": "ERROR"
473 },
474 "elasticsearch.trace": {
475 "handlers": ["file", "console"],
476 "level": "ERROR"
477 }
478 }
479 }
480 and start Glances using the following command line:
482 LOG_CFG=<path>/glances.json glances
484 NOTE:
486 Replace <path> by the folder where your glances.json file is hosted.
487
489 Monitor local machine (standalone mode):
490 $ glances
491 Monitor local machine with the web interface (Web UI), run the follow‐
493 ing command line:
494 $ glances -w
495 and open a Web browser with the returned URL
497 Monitor local machine and export stats to a CSV file:
499 $ glances –export csv –export-csv-file /tmp/glances.csv
500 Monitor local machine and export stats to a InfluxDB server with 5s
502 refresh time (also possible to export to OpenTSDB, Cassandra, Statsd,
503 ElasticSearch, RabbitMQ and Riemann):
504 $ glances -t 5 –export influxdb
505 It is also possible to export stats to multiple endpoints:
507 $ glances -t 5 –export influxdb,statsd,csv
508 Start a Glances server (server mode):
510 $ glances -s
511 Connect Glances to a Glances server (client mode):
513 $ glances -c <ip_server>
514 Connect to a Glances server and export stats to a StatsD server:
516 $ glances -c <ip_server> –export statsd
517 Start the client browser (browser mode):
519 $ glances –browser
