Simple custom monitoring of Linux services, only to see if the PS process exists

Create a custom script:

[[email protected] zabbix_agentd.d]# cat crm-web.sh #!/bin/bashps-ef|grep crm-web|grep-v ' grep ' |grep-v ' sh ' |wc-l

Note Permissions and Users:

[email protected] zabbix_agentd.d]# ll crm-web.sh-rwxr-xr-x 1 Zabbix Zabbix the 14:55 crm-web.sh

Create a custom key:

[email protected] zabbix_agentd.d]# cat crm-web_status.conf userparameter=crm-web_status[*],/etc/zabbix/zabbix_ Agentd.d/crm-web.sh $

Attention to permissions and users: (should not be adjusted)

[email protected] zabbix_agentd.d]# ll crm-web_status.conf-rw-r--r--1 root root-13:03 crm-web_status.conf

Restart the Zabbix Agent service:

In the new interface that pops up, fill in the following:

' Name ': Crm-web Service not available

"Expression": {10.253.40.86:crm-web_status.last ()}<>1

"Description": Crm-web Service Not available "is not required to fill in the content"

"Severity": Nor does it have to be this type

In the popup dialog box, click on "Crm-web service process". The reason for this is that the item is created earlier, otherwise the custom monitoring item does not appear here. If not, you can also check to see if the "Group" and "Host" in the upper-right corner are positioned correctly.

The basic configuration is in this context.

The following custom monitoring items are almost the same:

[[email protected] zabbix_agentd.d]# cat crm-notify.sh #!/bin/bashps-ef|grep crm-notify|grep-v ' grep ' |grep-v ' sh ' |wc-l [email protected] zabbix_agentd.d]# cat crm-notify_status.conf userparameter=crm-notify_status[*],/etc/zabbix/ Zabbix_agentd.d/crm-notify.sh $

Do not forget to restart the Zabbix agent service.

Execute the test command on the Zabbix server:

[Email protected] zabbix_agentd.d]# zabbix_get-s 10.253.40.86-k "Crm-web_status" 1[[email protected] zabbix_agentd.d] # zabbix_get-s 10.253.40.86-k "Crm-notify_status" 1
