SMS notifications when some services are down (monitoring)?

Question

Monitoring

It happens at work that some services stop responding. In the logs, errors such as failed sending error are written, from which we find out what does not work for us. But we will find out later after some time. That's why the question arose of how to make a script that will send SMS once again by the keyword, for example, failed sending. And we will know immediately which service or database has fallen. How can I do that???

Answer 1

Nobody sends SMS anymore.
All in telegram.
It's free. Conveniently. Easy to implement.

Answer 2

zabbix, cacti and others - specifically designed for monitoring, identifying trends and including notification of deviations from the norm

Answer 3

monit-it.ru
free tariff will do.
If it’s directly paid, then 500 r
is there and sms and mail and queues and even actions on the server and all this in a service without bulky zabbix
to start

Answer 4

SMS is really paid. in TG for free

Answer 5

Sasha Odarchuk as far as I understand Zabbix sends information on system notifications. Question, there are several applications/programs installed on OS RedHat Linux. Is it possible to set up an uptime robot so that notifications come from third-party applications. The installed software has its own work logs. From there, can Zabbix or uptime robot intercept in the logs the keywords for which it will notify by TG.
