Ok the reason for this is because --exclude-ns (and --ns) can take any number of arguments. you can include/exclude several namespaces at once. Therefore, the argument parser doesn't know that the log file name is actually your positional argument and not another namespace.

I'll try to find out if the usage can be changed to put the positional argument (filename) at the end.

I updated the usage string.

Now I can't exclude commands logs.
It doesn't show in the list of namespaces, but you can see them in graph.

I changed the log line parser and extract better info now. The commands are now using the actual namespaces that are in the log instead of "(command)". So for example admin commands have the namespace "admin.$cmd". You can exclude those but you need to escape the $ sign because I'm using the regex matcher.

Try this:

   mplotqueries mongod.log --exclude-ns "admin.\$cmd"

I can fix this too so the escape isn't needed.

ok cool. And how do I filter these out?

I usually use grep -v and a pipe to exclude all these:

    cat mongod.log | grep -v "LockPinger" | grep -v "writebacklisten" | mplotqueries

You can "pipe" log lines into mplotqueries as well. You can also combine it with mlogfilter and mlogmerge:

    mlogmerge mongod_prim.log mongod_sec.log mongod_arb.log --label [pri] [sec] [arb] | 
        grep -v writebacklisten | 
        mlogfilter --slow --from Jan 30 20:16 --to +1h | 
        mplotqueries --log
