SmokePing之配置文件config详解
这个配置文件不管在Linux下面还是在BSD下面是一致的。
如下解说：
整个config文件里面只有#是注释
第一部分 General 属于基本配置。值得注意的地方有imgcache和imgurl这两个参数，要注意一下，和apache配置相关联，如果配置不好的话，打开web的时候图片会显示不出来。
*** General ***
owner = Kevin Deng
contact =
mailhost = smtp.sohu.com
sendmail = /usr/sbin/sendmail
# NOTE: do not put the Image Cache below cgi-bin
# since all files under cgi-bin will be executed ... this is not
# good for images.
imgcache = /usr/local/smokeping/htdocs/img
imgurl = img
datadir = /usr/local/var/smokeping
piddir = /usr/local/var/smokeping
cgiurl =
smokemail = /usr/local/etc/smokeping/smokemail
tmail = /usr/local/etc/smokeping/tmail
# specify this to get syslog logging
syslogfacility = local0
# each probe is now run in its own process
# disable this to revert to the old behaviour
# concurrentprobes = no
第二部分Alerts 是属于报警配置， 这个我还没有测试过。以后再说
*** Alerts ***
to =
from =
+someloss
type = loss
# in percent
#pattern = >0%,*12*,>0%,*12*,>0%
#comment = loss 3 times in a row
pattern = ==S,>0%,>0%,>0%
comment = loss at startup
+rttdetect
type = rtt
# in milli seconds
pattern = <10,<10,<10,<10,<10,<100,>100,>100,>100
comment = routing mesed up again ?
第三部分 Database RRD数据库配置。step和pings这两个参数要在启动smokeping之前配置好，如果在smokeping启动后再配置这两个参数，需要把原来的rrd文件都删除，然后再启动smokeping才可以。所以这个一定要先配置好。默认是step=300 pings=20 应该是每300s内执行20次ping的动作
*** Database ***
step = 300
pings = 60
# consfn mrhb steps total
AVERAGE 0.5 1 1008
AVERAGE 0.5 12 4320
MIN 0.5 12 4320
MAX 0.5 12 4320
AVERAGE 0.5 144 720
MAX 0.5 144 720
MIN 0.5 144 720
第四部分Presentation 是关于网络状态的一些配置和解释，基本不需要更改
*** Presentation ***
template = /usr/local/etc/smokeping/basepage.html
charset = gb2312
+ charts
menu = Charts
title = The most interesting destinations
++ stddev
sorter = StdDev(entries=>4)
title = Top Standard Deviation
menu = Std Deviation
format = Standard Deviation %f
++ max
sorter = Max(entries=>5)
title = Top Max Roundtrip Time
menu = by Max
format = Max Roundtrip Time %f seconds
++ loss
sorter = Loss(entries=>5)
title = Top Packet Loss
menu = Loss
format = Packets Lost %f
++ median
sorter = Median(entries=>5)
title = Top Median Roundtrip Time
menu = by Median
format = Median RTT %f seconds
下面的overview和detail里面是图片大小设置，可以按需来设置
+ overview
width = 800
height = 50
range = 10h
+ detail
width = 800
height = 200
unison_tolerance = 2
"Last 3 Hours" 3h
"Last 30 Hours" 30h
"Last 10 Days" 10d
"Last 400 Days" 400d
+ hierarchies
++ owner
title = Host Owner
++ location
title = Location
第五部分Porbes 指针配置，我们一般只用到fping所以就只要以下配置就可以了，确定路径是否正确，这里还可以设置fping包的大小，参数是packetsize
*** Probes ***
+ FPing
binary = /usr/local/sbin/fping
packetsize = 2000
第六分部Slaves 主从关系里面的从服务器相关配置，smokeping里面从服务器只需要安装好就可以了，不需要配置，smokeping的所有配置都是在master上面设置。这里主要设置好secrets密码文件和从服务器配置就可以了。下面我配置了两个从服务器。一个是st，一个是fy
*** Slaves ***
#secrets=/home/oetiker/checkouts/smokeping/trunk/software/etc/smokeping_secrets.dist
secrets = /usr/local/etc/smokeping/slavesecrets.conf
#+boomer
#display_name=boomer
#color=0000ff
#location = HuaDong
+ st
display_name = ShanTou Monitor
color = 0000ff
#location = HuanDong
+ fy
display_name = FuYong
color = 00ff00
#++ override
#Probes.FPing.binary = /usr/bin/fping
第七部分 Targets 目标配置。在这里可以单独配置一台服务器的监控情况，需要从slave服务器上取值的配置也是在这里配置。我已经用注释说明的很清楚了。
这里要注意一下。+代表一级菜单 +下面的++是继承上面的+成为二级菜单。 而且可以有多个一级菜单和二级菜单。
*** Targets ***
probe = FPing
menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of ShenZhen Wang Yu Company. \
Here you will learn all about the latency of our network.
####### Slaves Configure ###########
+ Slaves
menu = Slaves
title = All of the Monitor From the Slaves
++ ShanTou
menu = ShanTou
title = Host 192.168.0.208 Monitor From Slaves
slaves = st fy
host = 192.168.0.208
++ FuYong
menu = FuYong
title = Host 192.168.0.210 Monitor From Slaves

host = 192.168.0.210

主/从 做分布式监控的时候有几点需要注意
1.主从服务器上面的密码文件权限必须为600 而且主服务器上面的密码文件的属主必须为apache的启动用户
2.从服务器上面的密码文件只需要一个密码就行，也就是主上面为它配置的那个密码。同样从服务器上面的密码文件的属主必须为smokeping的启动用户
下面是主/从做分布式监控时我碰到的问题，及解决办法。写了一个简单的FQA
Q:Slave启动的时候报错。
[root@Nagios etc]# /usr/local/smokeping/bin/smokeping --master-url= --cache-dir=/usr/local/smokeping/var/ --shared-secret=/usr/local/smokeping/etc/smokeping_secrets --slave-name=ShenZhen
WARNING: Opening secrets file /usr/local/etc/smokeping/slavesecrets.conf: Permission denied
ERROR: we did not get config from the master. Maybe we are not configured as a slave for any of the targets on the master ?
A:
在master上面 对slavesecrets.conf文件 执行如下命令：
chow smokeping slavesecrets.conf
Q:
[root@Nagios etc]# /usr/local/smokeping/bin/smokeping --master-url= --cache-dir=/usr/local/smokeping/var/ --shared-secret=/usr/local/smokeping/etc/smokeping_secrets --slave-name=ShenZhen
WARNING: Data from ShenZhen was signed with 58e8b1b17440aa40fac67161b8c7a328 which does not match our expectation
ERROR: we did not get config from the master. Maybe we are not configured as a slave for any of the targets on the master ?
A:
这个错误就是本地的密码文件配置错误，本地密码文件只保存master上面配置你这台slave的密码，只需要一个密码就可以了
Q:
[root@Nagios etc]# /usr/local/smokeping/bin/smokeping --master-url= --cache-dir=/usr/local/smokeping/var/ --shared-secret=/usr/local/smokeping/etc/smokeping_secrets
WARNING: No secret found for slave Nagios.kevinadmin.org
ERROR: we did not get config from the master. Maybe we are not configured as a slave for any of the targets on the master ?
A:
在master上面的密码文件里加上Nagios.kevinadmin.org及对应的密码就可以了。
Q:
[root@Nagios etc]# /usr/local/smokeping/bin/smokeping --master-url= --cache-dir=/usr/local/smokeping/var/ --shared-secret=/usr/local/smokeping/etc/smokeping_secrets
WARNING: I don't know the slave Nagios.kevinadmin.org ignoring it
ERROR: we did not get config from the master. Maybe we are not configured as a slave for any of the targets on the master ?
A:
这个是指在config文件里面没有定义Nagios.kevinadmin.org这个从服务器
