Tetragon PID will be used to retrieve memory stats using cgroup fs and thus the proc fs. Signed-off-by: Mahe Tardy <mahe.tardy@gmail.com>
pmap(1) is an utility that reads /proc/pid/smaps in a nicely format. This is the proper way of retrieving accurate memory usage per segment of a Linux process via /proc. Signed-off-by: Mahe Tardy <mahe.tardy@gmail.com>
We could also use CopyN using fileSrcInfo.Size() but it would silently copy empty files in the case of cgroup fs for example. Let's just display an error so that we can see what failed. Signed-off-by: Mahe Tardy <mahe.tardy@gmail.com>
Retrieve the memory cgroup and copy memory stat files. Some of these stats should be found in the metrics. Signed-off-by: Mahe Tardy <mahe.tardy@gmail.com>
