bash - How to customize PATH for sensu client? -


i have sensu client, debugged path in 1 of check script, , shows:

/sbin:/usr/sbin:/bin:/usr/bin:/etc/sensu/plugins:/etc/sensu/handlers

how can customize path sensu, say: want add /usr/local/bin end of path, results in: /sbin:/usr/sbin:/bin:/usr/bin:/etc/sensu/plugins:/etc/sensu/handlers:/usr/local/bin

i've tried many ways didn't success, i've tried:

  1. set sensu user's shell /bin/bash (instead of default /bin/false), , add .bashrc|.profile under sensu user's home dir /opt/sensu, line: export path=$path:/usr/local/bin
  2. edit /etc/default/sensu, add line path=$path:/usr/local/bin
  3. by reading this: https://sensuapp.org/docs/latest/clients, set user=ec2-user in /etc/default/sensu, after restarting sensu client, see sensu client process running ec2-user, however, surprisingly, path not same ec2-user

all 1,2 , 3 above didn't work, in check script written in python, have lins:

from subprocess import call, popen, pipe import os import sys import shlex  import platform print os.environ["path"]  proc = popen(['which', 'python'],         stdout=pipe,         stderr=pipe) out, err = proc.communicate() #does not return until process has terminated. print(out) print(err) #print(platform.__dict__) print(platform.python_version())  proc = popen(['whoami'],         stdout=pipe,         stderr=pipe) out, err = proc.communicate() #does not return until process has terminated. print(out) print(err) sys.exit(0)

the output was:

/sbin:/usr/sbin:/bin:/usr/bin:/etc/sensu/plugins:/etc/sensu/handlers /usr/bin/python    2.6.6  ec2-user

update, while wrote line in python check script: 

proc = popen(['bash','--login', '-x'], stdout=pipe, stderr=pipe) out, err = proc.communicate() print(out) print(err)

i saw output:

path=/sbin:/usr/sbin:/bin:/usr/bin:/etc/sensu/plugins:/etc/sensu/handlers:/usr/local/sbin:/usr/local/bin

however, other output surprisingly.... "which python" -> /usr/bin/python, "python --version" -> 2.6.6

request help....

so try add path in /etc/default/sensu

path=$path:/usr/local/bin

https://github.com/sensu/sensu-build/blob/master/sensu_configs/upstart/sensu-client.conf#l30

. /etc/default/sensu make work.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
