使用 netdata 監控 SNMP 設備試作

使用 netdata 監控 SNMP 設備試作

在 netdata 試裝 ( http://xrcd2.blogspot.tw/2017/06/netdata_21.html ) 後
,接著試透過 netdata 來做一般的 snmp monitor ,
其實大多數的網管軟體都提供這樣的基本功能,但以 netdata 來說,
還是需要一些 snmp 的基礎觀念.故整理一下之前所寫的一些基礎,
供需求的人參考之.

SNMP 基礎

本文開始

參考設定

https://github.com/firehol/netdata/blob/master/conf.d/node.d/snmp.conf.md

SNMP Data Collector

example:

{
"enable_autodetect": false,
"update_every": 5,
"max_request_size": 100,
"servers": [
{
"hostname": "10.11.12.8",
"community": "public",
"update_every": 10,
"max_request_size": 50,
"options": { "timeout": 10000 },
"charts": {
"snmp_switch.bandwidth_port1": {
"title": "Switch Bandwidth for port 1",
"units": "kilobits/s",
"type": "area",
"priority": 1,
"family": "ports",
"dimensions": {
"in": {
"oid": "1.3.6.1.2.1.2.2.1.10.1",
"algorithm": "incremental",
"multiplier": 8,
"divisor": 1024,
"offset": 0
},
"out": {
"oid": "1.3.6.1.2.1.2.2.1.16.1",
"algorithm": "incremental",
"multiplier": -8,
"divisor": 1024,
"offset": 0
}
}
},
"snmp_switch.bandwidth_port2": {
"title": "Switch Bandwidth for port 2",
"units": "kilobits/s",
"type": "area",
"priority": 1,
"family": "ports",
"dimensions": {
"in": {
"oid": "1.3.6.1.2.1.2.2.1.10.2",
"algorithm": "incremental",
"multiplier": 8,
"divisor": 1024,
"offset": 0
},
"out": {
"oid": "1.3.6.1.2.1.2.2.1.16.2",
"algorithm": "incremental",
"multiplier": -8,
"divisor": 1024,
"offset": 0
}
}
}
}
}
]
}

依據上述的範例,得知 netdata snmp data collector 的方式為 OIDs ,
以 Interface Traffic 來說,可以用 1.3.6.1.2.1.2.2.1.10.ifName ( Inbound )
用 1.3.6.1.2.1.2.2.1.10.ifName (Outgoing )取得流量使用資訊.

這時可以使用 snmpwalk + snmpget 來確定如何設定正確的 snmp.conf

以 Cisco 2960S Switch 為例

驗證 snmp plugin

( 可參考 https://github.com/firehol/netdata/blob/master/conf.d/node.d/snmp.conf.md
[ Testing the configuration ] 這一段的方式 )

[root@centos73 node.d]# /usr/libexec/netdata/plugins.d/node.d.plugin 1 snmp
/usr/libexec/netdata/plugins.d/node.d.plugin: line 2: exec: ERROR node.js IS NOT AVAILABLE IN THIS SYSTEM: not found

出現上述這訊息即為,未安裝 nodejs 套件

解法

#yum install epel-release
#yum install nodejs

驗證 nodejs

[root@centos73 node.d]# node --version
v6.10.3

裝好後再測試一次

[root@centos73 node.d]# /usr/libexec/netdata/plugins.d/node.d.plugin 1 snmp
2017-06-22 11:07:00: node.d.plugin: ERROR: snmp: 192.168.111.198: Received error = TypeError: snmp.varbindError is not a function

出現上述訊息則為 snmp.conf 設定錯誤,請利用 snmpwalk + snmpget 來確認 snmp 相關資訊的配置.

過關無誤則會出現以下資訊

[root@centos73 node.d]# /usr/libexec/netdata/plugins.d/node.d.plugin 1 snmp

configuring plugins

Most plugins come with auto-detection, configured to work out-of-the-box on popular
operating systems with the default settings.

However, there are cases that auto-detection fails. Usually the reason is that the
applications to be monitored do not allow netdata to connect. In most of the cases,
allowing the user netdata from localhost to connect and collect metrics, will
automatically enable data collection for the application in question
(it will require a netdata restart).

You can verify netdata plugins are able to collect metrics, following this procedure:

# become user netdata
sudo su -s /bin/bash netdata

# execute the plugin in debug mode, for a specific module.
# example for the python plugin, mysql module:
/usr/libexec/netdata/plugins.d/python.d.plugin 1 debug mysql

三論 SNMP OIDs

三論 SNMP OIDs

基礎入門

(1)利用SNMP OIDs 加入 Zabbix 監控
http://xrcd2.blogspot.tw/2012/10/snmp-oids-zabbix.html

(2)再論 SNMP OIDs
http://xrcd2.blogspot.tw/2012/10/snmp-oid.html

本文開始

(3)三論 SNMP OIDs

在 CheckPoint官網 DownLoad 該 MIB 以 R77 為例.
透過修改 snmpd.conf 的方式,可載入該 MIB.

[root@bbb /]# cat /etc/snmp/snmpd.conf
rocommunity public 127.0.0.1/32
MIB +/usr/share/snmp/mibs/CHECK-R77-MIB.txt
[root@bbb /]#

CHECK-R77-MIB 內文
.....

CHECKPOINT-MIB DEFINITIONS ::= BEGIN

-- SUBTREE: 1.3.6.1.4.1.2620.1
-- iso.org.dod.internet.private.enterprises.checkpoint.products

.....

checkpoint OBJECT IDENTIFIER ::= { enterprises 2620 }
products OBJECT IDENTIFIER ::= { checkpoint 1 }
tables OBJECT IDENTIFIER ::= { checkpoint 500 }
fw OBJECT IDENTIFIER ::= { products 1 }

.....

fwPolicyStat OBJECT IDENTIFIER ::= { fw 25 }

.......

fwNumConn OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"Number of connections"
::= { fwPolicyStat 3 }

.......

下面這個值是可以從上面的內文中看出....當然用 snmptranslate 這個最快...
但是要會找 MIB 文中的 Key Word...因為這才是根本的出處...
要不然 fwNumConn 這個東西怎麼來呢??!!

MIB OID ===> .1.3.6.1.4.1.2620.1.1.25.3.0
====> "Number of connections"

驗證

[root@bbb tmp]# snmptranslate -m CHECKPOINT-MIB -IR -On fwNumConn
.1.3.6.1.4.1.2620.1.1.25.3
[root@bbb tmp]#

[root@bbb tmp]# snmptranslate -m CHECKPOINT-MIB -IR -Onf fwNumConn
.iso.org.dod.internet.private.enterprises.checkpoint.products.fw.fwPolicyStat.fwNumConn
[root@bbb tmp]#

取得

[root@bbb tmp]# snmpget -v2c -c public 192.168.xxx.xxx .1.3.6.1.4.1.2620.1.1.25.3.0
SNMPv2-SMI::enterprises.2620.1.1.25.3.0 = Counter32: 2

那網管軟體就可以做 template 了,以 cacti 為例:

JDK 1.6.0_43 64 Bit 無法使用 jvm snmp

JDK 1.6.0_43 64 Bit 無法使用 jvm snmp ,一定要使用檔案的方式宣告方可使用.
之前使用直寫的方式,在 java 32 Bit 的版本是沒問題的.

另外一個問題是 /etc/hosts 一定要將主機名稱寫入,要不然 jmx 是無法使用
-Djava.rmi.server.hostname=192.168.x.x 這個參數!

java snmp 以檔案方式宣告如下:

tomcat startup.sh

export JAVA_OPTS="-Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m -Dcom.sun.management.config.file=/usr/local/tomcat/bin/snmp.properties -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.x.x. -Dcom.sun.management.jmxremote.port=9012 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"

[root@Test-Tomcat bin]# cat snmp.acl
acl = {
{
    communities = public
    access = read-only
    managers = localhost
}
}
[root@Test-Tomcat bin]# cat snmp.properties
com.sun.management.snmp.interface=0.0.0.0
com.sun.management.snmp.port=1610
com.sun.management.snmp.acl=/usr/local/tomcat/bin/snmp.acl

直寫方式如下:

export JAVA_OPTS="="-Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.xx.xx -Dcom.sun.management.jmxremote

tomcat Error: Failed to start SNMP adaptor with address

之前在測試 JVM SNMP + JMX 時,皆是以 Tomcat 做為 LAB 的測試標的.
但在使用 /usr/local/tomcat/shutdown.sh 將 tomcat 的服務停止時,
總會產生 tomcat Error: Failed to start SNMP adaptor with address 這樣的訊息.
最後總是直接使用 killall -9 去停止該項服務.最後 google 到解法.

資料參考 http://www.tikalk.com/java/forums/when-use-tomcat-catalina-opts-instead-java-opts

將 JMX & SNMP 的 JAVA_OPTS 從 /etc/profile.d/java.sh
移到 /usr/local/tomcat/startup.sh
在上方處放上原先設定:

export JAVA_OPTS="-Dcom.sun.management.snmp.port=1610 -Dcom.sun.management.snmp.acl.file=/usr/java/jre/lib/management/snmp.acl -Dcom.sun.management.snmp.interface=0.0.0.0 -Xms1024m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.100.101 -Dcom.sun.management.jmxremote.port=9012 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"

Cisco Router Interface Reliability Status Monitor ( DIY cacti template )

延續再論 SNMP OIDs http://xrcd2.blogspot.tw/2012/10/snmp-oid.html 這個主題,上次我已經提到如何將 Cisco Router Interface Reliability 加入 zabbix 的監控,這次我將同樣的SNMP OIDs 改成
cacti template 的方式,進行監控!
