What is VX-Log

VX-LOG is a data acquisition client based on Nxlog,and it will has some useful feature where NXLOG community version not has,such as line-number info for im-file module. and im_kafka and om_kafka module

VX-Log Features

File Line Number

line-number Info:line-number is a useful info when we collect data from file.we can use line-number info to do something like search log arround n line

Improve im_mark Info

make sure sigar is installed

git clone --depth=1 https://github.com/hyperic/sigar.git
./autogen.sh && ./configure && make CFLAGS=-fgnu89-inline && sudo make install

im_mark Input Module used to monitor agent status,But Nxlog provide info is not enough,so VX-LOG add VX-LOG cpu usage and memory usage
