<![CDATA[Linux Memory Monitoring]]>When I use Free or Available memory checks on Linux, it does not take into account the system cache.  This makes all my busy servers appear to have no memory to NetXMS because the systems start using all the free memory for file system caching.  Is there any way to take this into account?  Right now I'm checking for the use of swap to see if I'm really running out of memory -- I'd prefer not to do that and I would like to be able to check for free memory on my systems that have been intentionally configured without swap...

Thanks!

Still having this problem.  Any solutions out there?

Add following line to nxagentd.conf and create appropriate DCI for FreeMemPerc:

ExternalParameter = FreeMemPerc:awk '$$1=="MemTotal:" {total=$$2} $$1=="MemFree:" {free=$$2} $$1=="Cached:" {cached=$$2} END {printf("%.0f\n",(free+cached)/total*100)}' /proc/meminfo

How are you getting the data - from SNMP or nxagent?

nxagent

Because the answer depends on what you are using.
