Possibly before our 3.0 migration. |

Hello David, I'm trying to reproduce this issue. Could you please share the screenshot of top command and values from Zabbix frontend for the same period? Regards, |

top isn't installed on our Solaris, prstat output supplied instead. |

Does this affect only one host or it is a global issue? Could you please attach the Template you are using and the agent you are using? Did you've modified the Agent source code? Thanks! |

Zabbix Agent binary. |

The agent source code isn't modified, but the install paths are specific for our environment. |

Sorry for delay, Could you please double-check with the one we have on the download page(pre-compiled 3.2.0)? Do counters still false or no? |

I get the same incorrect information using the pre-compiled 3.2.0 binary: $ zabbix-agent/bin/zabbix_get -s localhost -k system.swap.size[,pfree] 100.000000 $ zabbix-agent/bin/zabbix_get -s localhost -k system.swap.size[,free] 34359734272 $ zabbix-agent/bin/zabbix_get -s localhost -k system.swap.size[,total] 34359734272 $ zabbix-agent/bin/zabbix_get -s localhost -k system.swap.size[,used] 0 $ zabbix-agent/bin/zabbix_get -s localhost -k system.swap.size[,pused] 0.000000 $ zabbix-agent/bin/zabbix_get -s localhost -k agent.version 3.2.0 $ memstat RAM Total: 131024 MB RAM Used: 121712 MB RAM Free: 9312 MB --------------------- Swap Total: 70711 MB Swap Used: 67418 MB Swap Free: 3292 MB |

In the documentation it is stated that
In the description example I can see that the value for the area (blocks) and area that is not currently allocated (free) are the same - the whole swap area is free (not allocated). Note that these values are the number of 512-byte blocks. So if we do the calculations: From all that I can conclude that swap reports on Solaris are working correctly. WON'T FIX |
