Monitoring RAM Usage Over SNMP

Detect High Memory Usage In Real-time

RAM is most precious and hard to fit into resource on most systems. To watch RAM usage is of crucial importance for systems that run such services as databases, cache services, Web servers and so on. IPHost Network Monitor provides you with tool to monitor RAM usage, using any SNMP protocol version (v1, v2c or v3).

SNMP Memory monitor can display either used, or free RAM amount. Use whatever of these metrics fits your needs. Free memory monitor can be used to indicate system low memory condition in case any memory-intensive processes are running.

You can read more on the above metrics in online help. Note it could be useful to monitor both metrics for the same host. When setting host’s software configuration, both amounts can be used to trigger a problem state. Hence, SNMP Memory monitor is a handful tool, for example,  to improve fine-tuning and performance monitoring of a Linux system.

Available RAM amount is typically fluctuating on real-life systems; depending on what is running on the network device, free memory amount usually changes within known bounds. To learn these bounds, set up monitor and let it run for at least one business day, to register all typical usage cases. After that, low and high memory usage values are known and state conditions can be set.

It is generally advised to set up monitoring other resources (such as network traffic, CPU usage etc), that would help to determine acceptable hardware resources values and see the trends in resources usage. If possible, create higher load situation on device, to gain data on how it would affect hardware resources monitors (CPU, Disk space and Memory monitors) values.

Note that if any changes are made to the system being monitored, it is advisable to re-adjust the hardware usage bounds as said above, to avoid both false alarms and situations when real outage happens.

WMI and SSH monitors for hardware stats

Looking for server monitoring software to control RAM usage and other hardware metrics? IPHost Network Monitor offers easy to use monitor types to handle this task. Apart from memory usage, SNMP can be used on variety of systems to monitor CPU load, count running processes, track disk usage and for monitoring a variety of other resources. Actually, SNMP agent can be set up to add any new variables in its tree, hence making it possible to use SNMP to monitor in same way arbitrary hardware or software piece used.

WMI (Windows Management Instrumentation) and SSH (Secure Shell) can be used instead of SNMP, on Windows and UNIX-like system, correspondingly. More than one method to access/modify system data can be available simultaneously for the same host.
