All results available in this file are formatted into multiples of KB, use cat, grep, awk or your favorite text manipulation command to get the desired result. Reading memory usage from this file is specially useful for scripting purpose. Find linux memory usage from the /proc/meminfo file It's one of the most used command to check memory usage in Linux or any UNIX like OS, even available in most embedded systems including WiFi routers running OpenWrt or DD-Wrt. Show linux memory usage in human readable form for 10 times with 0.5 second interval between results. -s, continuously print results with a delay.-c, display results many times,1 second delay.It's worth to pass few more command line arguments to get more convenient results. Just run the command like bellow, no root privilege required. To check available free memory and swaps, use the free command. Get realtime linux memory info with top and htop commandsĬheck Linux memory usage with the free command.Check linux memory usage with the atop command.Check installed memory size with dmidecode command.Find linux memory usage from the /proc/meminfo file.Check Linux memory usage with the free command.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.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.Typical apps will include Firewall, Captive Portal, and VPN apps. 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.
