Mongodb monitoring script

The script covers two ways to monitor mongo: using the built-in mongostat tool to view, the location of each monitoring item may have to be adjusted according to the actual mongostat output; and entering the admin library to view specific status information may need to be verified.

Complete steps:

1. Create user roles for monitoring: the permissions of mongo users are divided by user roles

> use admin > db.getRoles () > db.createRole ({role: "mongostatRole", privileges: [{resource: {cluster:true}, actions: ["serverStatus"]}], roles: []}) / / create a user role with mongostat command permissions

two。 Create a system monitoring role

> db.getUsers () > db.createUser ({user: "dbmon", pwd: "password", roles: [{role: "mongostatRole", db: "admin"}]})

3. Scripting, mongodb_sts.sh

#! / bin/bashhost= "127.0.0.1" passwd= "password" rst=''case "$1" in conn) rst= `mongostat-n 1-u dbbak-p $passwd-- authenticationDatabase=admin | awk 'NR==2 {print $(NF-1)}' `;; dirty) rst= `mongostat-n 1-u dbbak-p $passwd-- authenticationDatabase=admin | awk-F [\] + 'NR==2 {print $8}'` Used) rst= `mongostat-n 1-u dbbak-p $passwd-- authenticationDatabase=admin | awk-F [\] + 'NR==2 {print $9}' `;; qr) rst= `mongostat-n 1-u dbbak-p $passwd-- authenticationDatabase=admin | awk-F [\\ |] + 'NR==2 {print $(NF-7)}'` Qw) rst= `mongostat-n 1-u dbbak-p $passwd-- authenticationDatabase=admin | awk-F [\ |] + 'NR==2 {print $(NF-6)}' `;; res) res=$ (echo "db.serverStatus (). Mem" | mongo-u dbbak-p $passwd admin | awk-F [,\]'/ "resident" / {print $3}') rst=$ [res*1024*1024] Vsize) resize=$ (echo "db.serverStatus (). Mem" | mongo-u dbbak-p $passwd admin | awk-F [,\]'/ "virtual" / {print $3}') rst=$ [resize*1024*1024];; *) echo "aaaaaaaaaaaa" # exit 5esacif [- z $rst]; then echo 0else echo $rstfi

4. Script applications: cacti, zabbix, etc.
