如何在Nagios中的Nagiosgraph中設置對數縮放？

Question

我有圖表，我有數據，但我需要它的對數尺度，因爲我們要從幾十到二十萬個物品，並且變體幾乎不可能識別。

我看不到在哪裏/如何編輯正確的配置文件以獲得這組rrd圖以對數形式運行。

Answer 1

Nagiosgraph是rrdgraph的包裝器，並且使用它自己的配置文件。我發現rrdopts.conf可能是進行此更改的最佳位置。只需添加服務名稱，幷包含-o標誌（或--logarithmic）注意其他服務如何定義rrdgraph選項。

# rrd options for nagiosgraph 
# 
# This file contains per-service options for rrdgraph. The format is 
# service=options 
# where the options are standard rrdgraph command-line options. For example: 
# PING=-X 0 
# Load=-u 105 -l 0 
# The options will be applied to each graph matching the indicated service. 
# See rrdgraph for details about the options. 

# keep the ups plots in reasonable ranges 
ups-load=-u 105 -l 0 -r 
ups-charge=-u 105 -l 0 -r 
ups-temp=-u 45 -l 20 -r 
# memory counts are computer K not metric K, and always greater than 0 
mem=-l 0 -b 1024 
# do alternative autoscaling on the ntp graphs 
ntp=-A 
# cpu is always [0-100] 
cpu=-u 100 -l 0 -r 
# My custom check command needs logarithmic scaling -o option 
My_Custom_Service_Check_Command=-o
