How does Zabbix calculate uptime?

[Jarne St]

I have an item SystemUptime monitord by an snmp agent (snmp version 2).

I want to monitor the time that the system is running. (uptime)
In the latest data I see: 25 days, 03:33:20. But if I see go the value I see 2172853.

How does Zabbix compute the uptime from the value 2172853 to 25 days, 03:33:20?
Could anyone explain how this uptime is computed?

And how can I represent this uptime (25 days, 03:33:20, not the value, but 25 days) in Grafana in a SingleStat panel.

Any help would be welcome!

Hello you can use duration unit in Grafana

Common representation of uptime is number of seconds since system was booted. so:

2172853 / 60 / 60 / 24 = 25.148761574074074074074074074074. so 25 full days

0.148761574074074074074074074074 * 24 = 3.5702777777777777777777777777778 - 3 hours

0.5702777777777777777777777777778 * 60 = 34.216666666666666666666666666667 - 34 minutes

0.216666666666666666666666666667 * 60 = 13 - 13 second seconds
