Unsupported item key

[rlinux57]

I want to monitor mongodb through template. Zabbix server fetch the names of databases from mongodb server but unable to fetch the values and status of mongodb.
When i run below command on zabbix server i got an error:

#zabbix_get -s HOSTIP -k "mongodb.asserts.msg"
Output:
ZBX_NOTSUPPORTED: Unsupported item key

zabbix server is installed on centos 7.4

There is no key "mongodb.asserts.msg" as the item key which is prepared by the standard.
Perhaps it seems necessary to add a script or setting for specifying that key and getting the value.

Please carefully check the installation guide for that template.
