How to connect to cisco via telnet in ZABBIX, from there ping the machine via IP and get the result not as a string, but TRUE or FALSE?

Question

System administration

Created a monitoring element that uses the "TELNET agent" type. Connects fine.
Script to execute: ping IP address
Information type: character.
As a result, I get the result from cisco:

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to <i>IP-адрес</i>, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

And all this is recorded in history. I want the value TRUE or FALSE to be written to the history, depending on the result returned by the tsiska (in our case, !!!!! => TRUE).
How to transform the received result to the necessary form?
PS: by the way, I created a regular expression myreg that returns TRUE if we have "!!!!!", but I don't understand how and where to use it.
PPS: it would be nice to write down an integer value in order to then display a graph of the availability of the pinged machine.

Answer 1

I think it would be right to write an external script that will climb to the cisco from the Zabbix server, receive data and send it to monitoring.

Answer 2

In my opinion, it would be more correct to use IP SLA (if there is support) with passive (trap) or active snmp result retrieval.
