Probably the default scrape_timeout value is too short for you [ scrape_timeout: <duration> | default = 10s ] Set a bigger value for scrape_timeout. scrape_configs: – job_name: ‘prometheus’ scrape_interval: 5m scrape_timeout: 1m Take a look here https://github.com/prometheus/prometheus/issues/1438
Edit the prometheus.service file vi /etc/systemd/system/prometheus.service add “–storage.tsdb.retention.time=1y” below to “ExecStart=/usr/local/bin/prometheus \” line. So the config will look like bellow for 1 year of data retention. [Unit] Description=Prometheus Wants=network-online.target After=network-online.target [Service] User=prometheus Group=prometheus Type=simple ExecStart=/usr/local/bin/prometheus \ –config.file /etc/prometheus/prometheus.yml \ –storage.tsdb.path /var/lib/prometheus/ \ –web.console.templates=/etc/prometheus/consoles \ –web.console.libraries=/etc/prometheus/console_libraries \ –web.external-url=http://34.89.26.156:9090 \ –storage.tsdb.retention.time=1y [Install] WantedBy=multi-user.target

You can use the argument list of group_left to include extra labels from the right operand (parentheses and indents for clarity): ( max(consul_health_service_status{status=”critical”}) by (service_name,status,node) == 1 ) + on(service_name,node) group_left(env) ( 0 * consul_service_tags ) The important part here is the operation + on(service_name,node) group_left(env): the + is “abused” as a join operator (fine … Read more
I like tools that will perform more than one task, Notepad++ is a great notepad replacement and has a Document Monitor plugin (installs with standard msi) that works great.

Can “any” server handle it? Probably. Should you do it? Probably not. Ask yourself a few questions: How fast will you be to respond to an outage? How many pageviews do you normally receive per second? How many consecutive errors are you willing to see before calling it “Down” and sending an alert? Do you … Read more
not an answer really, but some pointers: definitivly take a look at presentation about nagios @ goldman sachs. they faced problems you mention – redundancy, scalability: thousands of hosts, also automated configuration generation. i had redundant nagios setup but at much smaller scale – 80 servers, ~1k services in total. one dedicated master server, one … Read more
This is a truly great question, and it’s a shame it has not gotten more love! My basic theory of bottleneck analysis is to treat the system as a box with 4 sorts of finite resources: processor, memory, disk, and network. So I want to get basic numbers for each of these to determine the … Read more
