Zabbix automatically discovers and monitors remote MongoDB instances based on host and port list

In some cases, you can only use a remote MongoDB instance and cannot log in to the server where the MongoDB instance resides. In this case, you can maintain a list of hosts and ports of a remote MongoDB instance on one server, and then use the low-level discovery feature of zabbix to automatically add corresponding monitoring based on the host and port.

MongoDB host and port discovery step mongodb_discovery.py

Host and port list file mongodb_servers.txt, where the host and port information of each instance is stored

Display the results:

{"data": [{"{# MONGO_HOST}": "192.168.5.7 MONGO_HOST 30000"}, {"{# MONGO_HOST}": "192.168.5.23 MONGO_HOST 30000"}, {"{# MONGO_HOST}": "192.168.5.23 MONGO_HOST 30002"} {"{# MONGO_HOST}": "192.168.5.23virtual 30003"}]}

two。 Get MongoDB port status information script discovery_mongodb_status.sh

Here, according to the value passed by {# MONGO_HOST}, the corresponding line will be found in the mongodb_servers.txt file with a colon ":" to determine the length of the entire line, and then use different mongodb connection methods.

Display the results:

$sh discovery_mongodb_status.sh uptime 192.168.5.23 sh discovery_mongodb_status.sh mem mapped 3000223823151 $192.168.5.23 sh discovery_mongodb_status.sh globalLock activeClients total 3000246691 $192.168.5.23 sh discovery_mongodb_status.sh globalLock activeClients total 300020

3. Add zabbix profile discovery_mongodb_status.conf that is automatically discovered by MongoDB

# echo "db.serverStatus () .mem.mapped" | mongo admin-- host xxxx-- port xxx-uroot-pxxxx#echo "db.serverStatus () .mem.mapped" | mongo 10.4.9.112:28018/admin-uroot-pxxxx#UserParameter=MongoDB.Status [*], / bin/echo "db.serverStatus (). $1.Secret2" | / data/app_platform/mongodb/bin/mongo admin-- port 28018 | sed-n '3p'UserParameter=MongoDB.Discovery / usr/bin/python / usr/local/zabbix/bin/mongodb_discovery.pyUserParameter=MongoDB.Discovery_Status [*], / usr/local/zabbix/bin/discovery_mongodb_status.sh $1 $2 $3 $4
