you all should install a munin probe so you can check all the system variables constantly and historically. It's a simple "apt-get install munin-node", opening of port 4949 and the connection configuration (1 line). I can run the host process if you like. We can then even compare uptimes

I'm on. Just set up a server and give me a hostname to connect to...
Despite UPS I've never reached an uptime of over a month with my B3 though, so I guess I'm out of contest...

Output of
aptitude show munin-node
does not make me feel confident I should let you probe me (or my system)

I haven't been reading up yet, but I guess there are settings for what it's allowed to probe?
If not, I could use my own offsite-backup-B1 instead

you can just enable the modules you want to show (uptime and load for example) and remove all the sensitive modules.
edit: I've put the stats for my B3 on a website: the observed hosts are fully anonymous. See if you approve of the security.

Well, I can't seem to find anything in there that I would say is too sensitive for me. Which modules do you have enabled?

Well, looking through the ones enabled by default I can't really see anything that seems dangerous. I don't want anyone seeing for example which files I have opened on my server, but this seems to be all statistics, right? The default ones are:
Code: Select all
apache_accesses
apache_processes
apache_volume
cpu
df
df_inode
diskstats
entropy
forks
fw_conntrack
fw_forwarded_local
fw_packets
hddtemp_smartctl
if_err_eth0
if_err_wlan0
if_eth0
if_wlan0
interrupts
iostat
iostat_ios
irqstats
load
memory
nfs4_client
nfsd
nfsd4
ntp_kernel_err
ntp_kernel_pll_freq
ntp_kernel_pll_off
ntp_offset
open_files
open_inodes
postfix_mailqueue
postfix_mailvolume
processes
proc_pri
smart_sda
swap
threads
uptime
users
vmstat

there are no default ones. The installer probes the system and makes an educated guess. In my opinion the NSF and NTP probes are useless. Also, the more probes, the longer it takes to query.

Ah. That's how it works. Well, I'll do some cleaning then. I also threw in a module for nut, makes sense to me.
So, how do I connect to your server?

Ah, the thing is that the server contacts you, but you must allow the server access. THis way you can always revoke acces yourself without being dependent on other people.
Basically you need to add two lines to /etc/munin/munin-node.conf
Code: Select all
allow ^80\.69\.76\.69$
host_name yourname.bubba
and then you need to let me know your IP address (do this via PM). Again only do this if you feel confident about this and that you know other people (especially me) can see some aspects of your machine that are normally not visible. I cannot imagine how this data can be abused, but everyone should make up their own mind.

Hello Cheeseboy,
It must be the wifi interface that causes the problems...
I have an uptime of 77 days, and 77 days ago a had a power outage here in the sity otherwise
the B3 would run from first startup

Hi Rene,
Well, that is one of the theories, but I have not been able to prove or disprove it yet.
In fact, it has been ages since I had the crash.
I have installed new software, removed other that I had no use for any more, and I regularly do apt-get upgrade, so who can tell?

Hmm I feel a bit silly here.
How do you know which ones are enabled?
I looked in:
munin-node.conf
plugin-conf.d/munin-node
And then there are 67 links in the plugins directory...
Did you just delete the unwanted links in the plugins dir?
I could not find a man page...

Seems we have a problem here. I sent you a PM at 15:40 (five hours ago) and it's still in my outbox. Anybody knows if there are problems with sending PM here?
