Problem It probably means that the systems requires more physical memory

[sby]

Hi,

How can i fix this issue.
I use KVM VPSen and want monitoring with zabbix.
I have CentOS 7 64 BIT en zabbix 3.0.1

I have this error every day.

It probably means that the systems requires more physical memory

Lack of free swap space on server1.demo.com

I hope some one can help me.

on which server you see it ?
the zabbix server or is it an agent alerting ? if its an agent check the swap
and if it is full.

please add more info

Hi,

I see this on a server where is installed a Zabbix Agent.
The Zabbix Agent is installed on a ubuntu 14.04 server.

The swap is normal in the server self.
Only zabbix say the error message

The swap is 0 in the ubuntu so the problem is solved.
Zabbix say it is a problem.

run this on zabbix server :

zabbix_get -s REMOTESERVERIP -p 10050 -I ZABBIXSERVERIP -k system.swap.size[,used]

and

zabbix_get -s REMOTESERVERIP -p 10050 -I ZABBIXSERVERIP -k system.swap.size[,free]

Replace ZABBIXSERVERIP with your zabbix server ip address
and REMOTESERVERIP on remote servers that making this issue,

and can you please post the trigger ?
my trigger looks like this :

{server.dev:system.swap.size[,pfree].last(0)}<50

pfree - show the percentage of swap space is free , you can run this as well - and if its 50% used space of swap space its alerting.

If the server doesn't have swap, monitoring it is useless. You should deactivate it.
I have the same situation on some OVH servers that I rent, they're configured by default with no swap space.

0

what is this server ? if you go to the server itself and run free -m what is the results ?
thats why zabbix fire a trigger about it , 0 make it think there is no space

[SBO]

That's what I said in my first post in this thread.. The server has no swap, it's useless to monitor it..

Hi,

Thank you i have now disabled the message so when i try free -m i see 0 so thank you for your help.

Hello zabbix community,

Sorry re-open this post.
I have the same problem but I think I have a swap.
This is what I have as a result with 'zabbix_get' (images)



REMOTESERVERIP = 192.168.4.14 (WINDOWS)
ZABBIXSERVERIP = 192.168.4.135 (CENTOS 7)

Thank you in advance for your help.
