Ubuntu system monitor inaccurate1/23/2024 ![]() It resets to 0 if the uptime exceeds this value. So, considering the calculation for 32-bit counters above, the maximum uptime that the SNMP System Uptime sensor can show on Windows is 49.7 days. Windows returns the uptime value of the default hrSystemUptime counter in thousands of seconds (1/1000). If you use the SNMP System Uptime sensor on Windows systems, you might encounter the issue that the uptime value resets to zero not only every 497 days but more often. ![]() Unfortunately, the behavior on Windows systems is different. This calculation applies to all network hardware devices, for example, switches or routers. If the uptime exceeds this value, that is, the monitored device runs longer than 497 days, the counter resets to 0 and, from this time on, PRTG shows uptime values that are lower than they actually are. Because the returned uptime value is given in hundreds of seconds (1/100), the maximum possible uptime that the sensor can display is 497 days (which is 4294967296 hundreds of seconds). This means that the maximum value that these counters can have is 2^32 (2 to the power of 32), which is the integer 4294967296. ![]() Wrong uptime values because of 32-bit countersīoth OIDs that the sensor can query for system uptime are 32-bit counters. There are two possible reasons for this: 1. However, in specific cases, PRTG reports an uptime that is lower than the real uptime of the monitored device. The sensor queries hrSystemUptime if available and uses sysUpTimeInstance as fallback, so the SNMP System Uptime sensor usually reports the correct uptime value. There are two possible OIDs to query uptime data from a device via SNMP: For a general introduction, see How do SNMP, MIBs, and OIDs work? For this purpose, PRTG queries the data from the device via the Simple Network Management Protocol (SNMP) and uses specific object identifiers (OIDs) to get the corresponding values. The SNMP System Uptime sensor monitors the time that a device runs. You're humans, we're humans, talk to us like humans.This article applies as of PRTG 22 Incorrect system uptime via SNMP This forum is useless except for the most basic issues people are having, anything that's an actual bug or actual issues no one seems to know how to fix or don't care.Īt least be real human beings with us and level with us instead of posting these robot-like polite PR answers. I'm sorry, there's no way you guys can go through your day thinking any of your responses actually helps users. You're not real tech support, you're not real moderators, you're just people doing the bare minimum to make this forum seem active so Spotify can say they're listening to user feedback when they obviously aren't. Seriously, as the OP said, every single one of you posting this overly polite PR tech support bot responses aren't helping, you're just blatantly adding to the enshittification of this service. You guys should be ashamed of yourselves for even calling your comments help, and more so ashamed to have marked this as "Solved." How can we actually make this a bug report and not just arbitrary copy and paste of basic troubleshooting tips or telling us to completely uninstall and reinstall?
