How do I monitor network buffer usage?
Issue
- Give a network buffers sysctl setup as:
Add the below to /etc/sysctl.conf:
net.ipv4.tcp_mem = 196608 262144 4194304
net.ipv4.tcp_wmem = 4096 16384 4194304
net.ipv4.tcp_rmem = 4096 87380 4194304
net.core.rmem_max = 18388608
net.core.wmem_max = 18388608
- How do we find out if is it enough? How much of it is being used?
