Dear Grafana Community,

my dashboard does not show any security updates since ca. 2 weeks.

Here are my settings:

/etc/apt/apt.conf.d/60prometheus-metrics
			
APT::Update::Post-Invoke-Success {"/usr/share/apt-metrics | sponge /var/lib/node_exporter/textfile_collector/apt.prom || true"};
DPkg::Post-Invoke {"/usr/share/apt-metrics | sponge /var/lib/node_exporter/textfile_collector/apt.prom || true"};


# Grafana - Displays the reboot status
@reboot /usr/share/apt-metrics | sponge /var/lib/node_exporter/textfile_collector/apt.prom || true

Do any of you have an idea or another solution?

LG, Martin
