[collectd] segfault in notify_email
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi all, I'm using collectd 4.10.1 (Debian sid stock package) and I'm experiencing segfaults in notify_email quite a few times a day. Syslog : Aug 26 23:03:58 evangeline kernel: [2532564.880645] collectd[7394]: segfault at 0 ip (null) sp 7fff6b0d1cb8 error 14 in collectd[40+21000] Backtrace : #0 0x in ??

Also, there is another minor bug : if collectd is stopped when a notification is dispatched, notify_email_shutdown() destroys the session which is used by notify_email_notification() causing a segfault. I can provide more information if needed. - -- regards, Manuel CISSE -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkx3aREACgkQOMej/7dX0BBFMACggZMfiVFp0+EfJJZGF8E/p4gC AIsAn324DfxVBBIYrwWZ8nptM4FggMi8 =NbSp -END PGP SIGNATURE- ___ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd

RRD files should be in /var/lib/collectd/rrd/www.mysite.com by default. Did you specify another dir in your collectd.conf (DataDir in the rrdtool plugin section) ? Also, you may take a look at cgp[1], a web based front-end to collectd written in php.

If you're using the package on lenny, it should be version collectd 4.4, the bind plugin is available since 4.6. You should either compile a more recent version of collectd or install a more recent package. -- regards, Manuel CISSE ___ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd
[collectd] huge values with tail plugin
Hi all, I'm using the tail plugin to monitor exim traffic and ssh failed/invalid login. My configuration (see below) is pretty much the same as in the man page, but from time to time I have huge values (last was 229.1M for "Local delivered") in the RRD database. Does anybody what could be causing this behaviour? Any problem in my config? regards, Manuel P.S.: relevant part of my config: Instance "Failed SSH attempts" Regex "Failed password" DSType "CounterInc" Type "counter" Instance "Failed password" Regex "Failed password for invalid user" DSType "CounterInc" Type "counter" Instance "Invalid users" Instance "Exim" Regex "S=([1-9][0-9]*)" DSType "CounterAdd" Type "ipt_bytes" Instance "Transferred bytes" Regex "\\" DSType "CounterInc" Type "counter" Instance "Local delivered" ___ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd
