Demo Zabbix LLD (low-level Discovery) how to use

2016/11/30

Objective: To monitor the needs of multiple buckets on couchbase to illustrate how Zabbix LLD works.

About LLD, the article on the network is also quite a lot of, I hope I can write a simple and clear howto to help beginners.

First, the preparatory work

1, "Zabbix-agent"

1) Script Example

[[email protected] scripts]# cat monitor_couchbase.sh   #!/bin/bash# #2016/ 11/25#v1.3#pc#echo  "[' Date '] $1 $2 $3"  >>/tmp/test.logcb_opts= '-c  127.0.0.1:8091 -u administrator -p xxx ' curl_opts= '-s -u administrator:xxx  Http://127.0.0.1:8091/pools/default/buckets ' # #usage () {    cat <<_eofusage:   $0  [cluster_info|cluster_list|cluster_healthy]         $0  [node_healthy|node_active]        $0   [bucket_list|bucket_info|bucket_lld]_eof}###### cb cluster details ##### #cb_cluster_ info () {    /opt/couchbase/bin/couchbase-cli server-info  $CB _opts}cb_cluster_list () {    /opt/couchbase/bin/couchbase-cli server-list  $CB _opts}cb_cluster_healthy ( ) {&NBSP;&NBSP;&NBSP;&NBSP;CB_CLUster_list |grep -o  ' 8091 healthy active '  |wc -l}###### cb current  node status ##### #cb_node_healthy () {    local stat= ' Cb_cluster_info  |jq  '.

2) zabbix-agent Configuration Example

[Email protected] scripts]# cat/etc/zabbix/zabbix_agentd.d/userparameter_couchbase.conf # # Clusteruserparameter= Couchbase.cluster.healthy[*],/bin/bash/etc/zabbix/scripts/monitor_couchbase.sh cluster_healthy## Nodeuserparameter=couchbase.node.healthy[*],/bin/bash/etc/zabbix/scripts/monitor_couchbase.sh node_ Healthyuserparameter=couchbase.node.active[*],/bin/bash/etc/zabbix/scripts/monitor_couchbase.sh node_active## Bucketuserparameter=couchbase.bucket.discovery[*],/bin/bash/etc/zabbix/scripts/monitor_couchbase.sh bucket_ Llduserparameter=couchbase.bucket.get[*],/bin/bash/etc/zabbix/scripts/monitor_couchbase.sh bucket_info

3) Restart Zabbix-agent

[Email protected] scripts]# service zabbix-agent restart

2, "Zabbix-server"

1) test the data obtained from the discovery

[[email protected] ~]# zabbix_get -s 10.50.200.33 -k  ' Couchbase.bucket.discovery '                    {         "Data": [                 {                           "{#BUCKETNAME}":  "account"                  },                 {                          "{#BUCKETNAME}":  "BBS"                  },                 {                          "{#BUCKETNAME}":  "Client"                  },                 {                          "{#BUCKETNAME}":   "Pay"                 },                 {                           "{#BUCKETNAME} ":  Shop"                  }        ]}

2) The format shown above is the data expected from the execution of the Zabbix LLD.

Ii. Configuring templates and corresponding LLD rules on the Zabbix web

1) Create a new template: Zbx_couchbase

2) in the template, select "Discovery Rules", add a rule name: "Couchbase.bucket.discovery", the focus is:

A. In "Key", fill in the name defined in the previous section in Zabbix-agent: "Couchbase.bucket.discovery"

B. Add a Macro to the section "Filters": {#BUCKETNAME} (this name is defined in the script in the previous section and can be customized)

3) The next step is to add a few "item prototypes" to the difference between the normal item: the Macro defined in the previous step is referenced in Key, example:

Name:couchbase bucket [{#BUCKETNAME}]-quotapercentusedkey:couchbase.bucket.get[{#BUCKETNAME},quotapercentused]

Note: After the LLD executes, the corresponding value of each {#BUCKETNAME} will be obtained and automatically generate the corresponding Item, which can be understood as a looping operation.

4) The next step is to create the corresponding "Trigger prototypes", which is not mentioned here;

5) Of course, you can also add a few ordinary items,triggers,graphs in this template, this is omitted;

6) Please refer to the example of the accompanying drawings.
