Monitoring

Alerting

• base rate fallacy: given 1% false positive, 1% false negative, and 99.9% uptime: 9.1% chance positive predictive value (true positive)
• sensitivity (% true positives) vs specificity (% not false positive)
• ‘Alert liberally; page judiciously. Page on symptoms, rather than causes.’
• ‘An alert should communicate something specific about your systems in plain language: “Two Cassandra nodes are down” or “90% of all web requests are taking more than 0.5s to process and respond.”’
• ‘Not all alerts carry the same degree of urgency.’
• ‘Many alerts will not be associated with a service problem, so a human may never even need to be aware of them. […] should generate a low-urgency alert that is recorded in your monitoring system for future reference or investigation but does not interrupt anyone’s work.’

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

ELK (Elasticsearch Logstash Kibana)

Though we're focused more on server setup procedure in this document, I will still give a very brief explanation in laymen terms for ELK. To those who are starting new in this stack, must have already heard of MVC (Model View Controller), so take it like this:

• Model => Elasticsearch (for Storage, Indexing & Search)
• View => Kibana (for DataViz & G-Man, yeah the one in half life 😏)
• Controller => Logstash (For Logs & Filtering)

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.
