This helper script is useful for parsing a bpftool map dump and determining whether or not duplicate maps are loaded (as indicated by their map name). It's not a perfect solution, but is helpful for rough debugging locally when something is not working right in Tetragon. When run on a file containing bpftool map output, the result will be a list of map names and their respective counts, sorted by count. Numbers higher than 1 are considered suspicious unless the map is OK to be duplicated (e.g. a "*heap" map in Tetragon.) Signed-off-by: William Findlay <[email protected]>
