Snmpget -v2c -c public $ip HOST-RESOURCES-MIB::hrSWRunPerfMem. Snmpget -v2c -c public $ip HOST-RESOURCES-MIB::hrSWRunPerfCPU.$pid HOST-RESOURCES-MIB::hrSWRunPerfMem is the total amount of real system memory allocated to this process. This file is used by the free, top, ps, and other system information commands. Note that on a multi-processor system, this value may increment by more than one centi-second in one centi-second of real (wall clock) time. The simplest way to check the RAM memory usage is to display the contents of the /proc/meminfo virtual file. HOST-RESOURCES-MIB::hrSWRunPerfCPU is the number of centi-seconds of the total system's CPU resources consumed by this process. you should know the process id(pid) of the process you want to monitor.snmp should be configured to accept requests from where you will run the script below(it may be configured in nf).the device running the process should have snmp installed and running.Check for large amounts of report processing.ĭo you have any of the advanced logging options in Config > Network > Advanced enabled (they're the last four options)? Disabling those can help lower your resource consumption.You may use SNMP to get the memory and cpu usage of a process in a particular device in network :).We have a default rule in Config > Network > Bypass Rules which is not enabled by default, but turning that on can help reduce memory usage. (Phish Blocker also uses the same database as Virus Blocker Lite, so it's also memory-intensive.) These apps only scan SMTP port 25 traffic, so if you don't have an on-premise email server, they're not doing anything for you. Uninstall Spam Blocker and Phish Blocker if they're not being used.The Linux kernel tries to make use of as much memory as it can, using some of it for buffers (temporary data storage) and caches (areas that store frequently accessed data) to speed up system performance. Typical apps will include Firewall, Captive Portal, and VPN apps. Interpreting Memory Usage On Linux, it’s important to understand that free memory is, essentially, wasted memory. Uninstall applications that are running but have no rules enabled or otherwise aren't being used.
If it's a temporary disabling, you can leave it, but if the app isn't going to be used in the near future we recommend uninstalling it entirely. This will be anything that's installed but not running. *Please note that the full version of Virus Blocker uses a different database than Virus Blocker Lite and is significantly lighter on RAM. Intrusion Prevention also runs at about 300 MB by itself, with more RAM required for additional blocking rules. The #1 culprit here is Virus Blocker Lite*, which requires about 600 MB of RAM. Disable and uninstall memory-intensive applications.With that said, if you'd like to reduce your NG Firewall's RAM consumption - particularly important on devices with 2 GB or RAM or less - here are some things you can do: On Linux-based software like NG Firewall, high RAM usage isn't necessarily a bad thing.
