写在前面
- 原以为不会再用到
smokeping，结果我错了。
- 据上次使用约半年，平常都是1次性用、这次又要用，完全忘干净了。
那么开始
安装
apt-get -y install smokeping
配置服务
- Web服务器的配置参考前面写的 用Nginx跑Shell脚本。
- 探测服务建议将
/etc/init.d/smokeping里配置的启动用户和Nginx保持一致，以www-data为例：
# /etc/init.d/smokeping
DAEMON_USER=www-data
- 跑出来的效果大概如下：
数据配置
- 页面模板
/etc/smokeping/basepage.html，其中的变量来自/etc/smokeping/config.d/General。
- 数据文件存放路径在
/etc/smokeping/config.d/pathnames，改路径记得修正目录权限。
# /etc/smokeping/config.d/pathnames
sendmail = /usr/sbin/sendmail
imgcache = /data/smokeping/htdocs/images
imgurl = images
datadir = /data/smokeping/libdata
piddir = /var/run/smokeping
smokemail = /etc/smokeping/smokemail
tmail = /etc/smokeping/tmail
- 主配置文件
/etc/smokeping/config里指定了所引用的配置，如下添加了 HTTP、Ping 的监测任务：
# /etc/smokeping/config
@include /etc/smokeping/config.d/General
@include /etc/smokeping/config.d/Alerts
@include /etc/smokeping/config.d/Database
@include /etc/smokeping/config.d/Presentation
@include /etc/smokeping/config.d/Probes
@include /etc/smokeping/config.d/Slaves
@include /etc/smokeping/config.d/Targets
@include /etc/smokeping/config.d/HTTP
@include /etc/smokeping/config.d/Ping
- 添加一个Ping的探测
/etc/smokeping/config.d/Ping：
+ demo-intranet-fping
probe = FPing
menu = 核心机房Fping内网
title = 机房内网Ping
++ demo-bfs-01
menu = demo-bfs-01
title = demo-ops-lvs-02 -> 192.168.1.1
host = 192.168.1.1
++ demo-cache-01
menu = demo-cache-01
title = demo-ops-lvs-02 -> 192.168.1.5
host = 192.168.1.5
++ demo-k8s-master-01
menu = demo-k8s-master-01
title = demo-ops-lvs-02 -> 192.168.1.32
host = 192.168.1.32
- 添加一个独立的HTTP监控，
/etc/smokeping/config.d/HTTP：
+ kisjd-http-curl
probe = Curl
menu = 监控HTTP响应时间
title = 测试出网的HTTP访问速度
++ baidu
menu = baidu.com
title = www.baidu.com
host = www.baidu.com
++ bilibili
menu = bilibili.com
title = www.bilibili.com
host = www.bilibili.com
++ youku
menu = youku.com
title = www.youku.com
host = www.youku.com
++ iqiyi
menu = iqiyi.com
title = www.iqiyi.com
host = www.iqiyi.com
- 配置文件
/etc/smokeping/config.d/Probes中指定了探测方法，示例：
*** Probes ***
+ AnotherSSH
forks = 24
offset = 90%
greeting = SSH-2.0-OpenSSH_Smokeping
interval = complete
mininterval = 0.8
+ Curl
binary = /usr/bin/curl
forks = 24
offset = 90%
agent = User-Agent: Smokeping/2.6.9
expect = OK
extraargs = -4 --head
extrare = / /
follow_redirects = no
include_redirects = no
insecure_ssl = 1
interface = bond0
timeout = 20
urlformat = http://%host%/
+ FPing
binary = /usr/bin/fping
blazemode = true
hostinterval = 1.5
mininterval = 0.001
offset = 50%
packetsize = 5000
pings = 20
sourceaddress = 10.130.1.73
step = 300
timeout = 1.5
tos = 0x20
usestdout = true
- 默认概览在配置文件
/etc/smokeping/config.d/Presentation中设定，如下添加了各多维度的数据供参考：
# /etc/smokeping/config.d/Presentation
*** Presentation ***
template = /etc/smokeping/basepage.html
charset = utf-8
+ charts
menu = 质量排行榜
title = 质量最差的排行榜
++ stddev
sorter = StdDev(entries=>4)
title = 响应时间方差排行 - top4
menu = 响应时间方差
format = Standard Deviation %f
++ max
sorter = Max(entries=>5)
title = 最大响应时间排行 - top5
menu = 最大响应时间
format = Max Roundtrip Time %f seconds
++ loss
sorter = Loss(entries=>5)
title = 稳定性最差的排行 - top5
menu = 稳定性
format = Packets Lost %f
++ median
sorter = Median(entries=>5)
title = 平均响应时间最差的排行 - top5
menu = 平均响应时间
format = Median RTT %f seconds

height = 50
range = 24h
