Keeping traffic stats after a reboot

[ColinTaylor]

Can you SSH into the router and post the output of these commands:

ps w | grep rstats
ls -l /var/lib/misc/
free
df -h
mount

I hope I've done this correctly. This is what happened after pasting in the above commands:

That all looks fine. You missed out the output of the mount command.

Try this:

service restart_rstats

ls -l /var/lib/misc/

P.S. Post terminal output inside a CODE block for readability.

I've executed each line of code one at a time. Was that the right way to do it? It doesn't seem to have solved the problem and I'm still only getting a few minutes of log data, so that's another problem.

I'm not sure what you mean in your postscript comment.

Could it be that I'm going to need to do a complete reset of my router to clear these problems?

Did the output of ls -l /var/lib/misc/ show anything different after you did service restart_rstats?

It might come to that.

Post the output of the mount command.

After executing the two commands above, I get this:

and this is what I get after the mount command:

That looks like it's working now.

Well there's good news and bad news. The bad news is that after rebooting this morning, the problem remains with the traffic stats. The good news is that after disabling Skynet, the system log returned to normal, so I've uninstalled Skynet.

 

[TheLyppardMan]

I'm going to try using a different flash drive for the traffic stats (which I'll probably format to NTFS), rather than storing them on the one I use for scripts. I have ordered a SanDisk drive from Amazon, which is supposed to be arriving by 10:00 PM today. I'll update this discussion when I have anything further to report.

 

[TheLyppardMan]

I've just installed a SanDisk 32GB flash drive and set that to be where the traffic stats will be saved. I'll reboot the router in the morning, when no-one else is using the network and see what happens.

 

[TheLyppardMan]

I can confirm that the traffc stats have survived a router reboot this morning. I'm not sure whether this is because they are now being saved to a different flash drive (formatted to NTFS) to the one used for scripts or whether it is because I have removed the space in the folder name. Also, the system log is working normally now.

It may be working now, but my thoughts went to the filesystem. IIRC (and this was a long time ago with a different model than I have now) it was important to format EXT4 with the -O no_journal option.

My thinking was that maybe the status were lost due to a journal flushing (or not) at shutdown.

No, always use journaling. The whole point of journaling is to prevent this kind of data loss.

On the syslog situation, I put Skynet back on and added four countries to ban, i.e., Russia, North Korea, China and Iran. I then checked the syslog and it was back to only showing entries for the last few minutes. I uninstalled Skynet and this morning I reinstalled it but didn't add any banned countries. The problem didn't materialise. I'll try adding those countries again but one at a time, to see if I can reproduce the problem. If I can, then I supoose I ought to start another discussion related to that issue only.
