Package: munin-plugins-core Version: 2.0.44-1~bpo9+1 Severity: normal Dear Maintainer,
I have noticed that postgres_connections_* graphs started rendering zero height graphs after upgrading munin from Streth Backports. This is output example: ``` # munin-run postgres_connections_ALL active.value 0 idle.value 0 idletransaction.value 0 unknown.value 0 waiting.value 0 ``` Please see screenshot attached. There's no way numbers should be actually zero - this is production system, and this reproduced on three different machines. Other plugin, like postgres_connections_db, still works fine: ``` munin-run postgres_connections_db db_v2.value 29 postgres.value 0 template1.value 0 ``` There are no relevant error messages in munin-node.log. -- System Information: Debian Release: 9.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.18.0-0.bpo.1-amd64 (SMP w/6 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages munin-plugins-core depends on: ii munin-common 2.0.44-1~bpo9+1 ii perl 5.24.1-3+deb9u5 Versions of packages munin-plugins-core recommends: ii libnet-snmp-perl 6.0.1-2 Versions of packages munin-plugins-core suggests: ii acpi 1.7-1+b1 ii conntrack 1:1.4.4+snapshot20161117-5 pn default-mysql-client <none> ii ethtool 1:4.8-1+b1 ii hdparm 9.51+ds-1+deb9u1 pn libcache-cache-perl <none> ii libdbd-mysql-perl 4.041-2 ii libdbd-pg-perl 3.7.4-1~pgdg90+1 ii libhttp-date-perl 6.02-1 ii liblwp-useragent-determined-perl 1.07-1 ii libnet-dns-perl 1.07-1 ii libnet-ip-perl 1.26-1 pn libnet-irc-perl <none> pn libnet-ldap-perl <none> ii libnet-netmask-perl 1.9022-1 pn libnet-telnet-perl <none> ii libxml-parser-perl 2.44-2+b1 ii libxml-simple-perl 2.22-1 ii lm-sensors 1:3.4.0-4 ii logtail 1.3.18 ii net-tools 1.60+git20161116.90da8a0-1 ii python3 3.5.3-1 ii ruby 1:2.3.3 ii smartmontools 6.5+svn4324-1 -- no debconf information
