Package: collectd Version: 4.10.1-1+squeeze1 Severity: important Tags: upstream
Those who do not learn from the past, are bound to repeat the same errors forever. collectd does not use UTC. Yet, it expects to be able to ignore timezone shifts that happen twice an year on a very very large number of systems. It results in this sort of crap: collectd[2139]: Filter subsystem: Built-in target `write': Dispatching value to all write plugins failed with status -1. collectd[2139]: uc_update: Value too old:name = <REMOVED>/temperature-temp1; value time = 1287260393; last cache update = 1287260393; being logged to syslog, for an entire hour. And it obviously inserts a lot of bogosity in the RRD. It needs to detect transitions in and out of DST, and do the right thing. If it doesn't want to deal with this, it MUST use UTC. Entering DST (non-UTC wall time goes forward): cleanly skip one hour (leave a hole in the RRD). Leaving DST (non-UTC wall time goes backwards): do NOT log to the RRD either the hour preceding the DST->ST change, or the hour right after the DST->ST change. Maybe RRDtool safeties against braindamage will already enforce this (I didn't test). And, obviously, log just ONCE to syslog that it is dealing with timezone shift. -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32.23 (SMP w/8 CPU cores) Locale: LANG=pt_BR.UTF-8, LC_CTYPE=pt_BR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages collectd depends on: ii collectd-core 4.10.1-1+squeeze1 statistics collection and monitori ii libc6 2.11.2-6 Embedded GNU C Library: Shared lib ii librrd4 1.4.3-1 time-series data storage and displ Versions of packages collectd recommends: ii iptables 1.4.8-3 administration tools for packet fi ii libatk1.0-0 1.30.0-1 The ATK accessibility toolkit ii libc6 2.11.2-6 Embedded GNU C Library: Shared lib ii libcairo2 1.8.10-6 The Cairo 2D vector graphics libra ii libcurl3-gnutls 7.21.0-1 Multi-protocol file transfer libra ii libdbi0 0.8.2-3 Database Independent Abstraction L ii libdbus-1-3 1.2.24-3 simple interprocess messaging syst ii libdbus-glib-1-2 0.88-2 simple interprocess messaging syst ii libesmtp5 1.0.4-5 LibESMTP SMTP client library ii libfontconfig1 2.8.0-2.1 generic font configuration library ii libfreetype6 2.4.2-1 FreeType 2 font engine, shared lib ii libgcrypt11 1.4.5-2 LGPL Crypto library - runtime libr ii libglib2.0-0 2.24.2-1 The GLib library of C routines ii libgtk2.0-0 2.20.1-1+b1 The GTK+ graphical user interface ii libhal1 0.5.14-3 Hardware Abstraction Layer - share pn libmemcached5 <none> (no description available) ii libmysqlclient16 5.1.49-1 MySQL database client library ii libnotify1 [libnotify1-gtk2 0.5.0-2 sends desktop notifications to a n pn libopenipmi0 <none> (no description available) pn liboping0 <none> (no description available) ii libpango1.0-0 1.28.1-1 Layout and rendering of internatio ii libpcap0.8 1.1.1-2 system interface for user-level pa ii libperl5.10 5.10.1-14 shared Perl library pn libpq5 <none> (no description available) pn libprotobuf-c0 <none> (no description available) ii libpython2.6 2.6.6-3 Shared Python runtime library (ver ii librrd4 1.4.3-1 time-series data storage and displ ii libsensors4 1:3.1.2-6 library to read temperature/voltag ii libsnmp15 5.4.3~dfsg-1 SNMP (Simple Network Management Pr ii libssl0.9.8 0.9.8o-2 SSL shared libraries pn libtokyotyrant3 <none> (no description available) ii libupsclient1 2.4.3-1+b1 network UPS tools - client library ii libvirt0 0.8.3-3 library for interfacing with diffe ii libxml2 2.7.7.dfsg-4 GNOME XML library pn libyajl1 <none> (no description available) collectd suggests no packages. -- Configuration Files: /etc/collectd/collectd.conf changed [not included] -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
