Cloud Native Monitoring
This is the primary benefit of push-based monitoring in a dynamic environment with short-lived activities
It captures data when it is generated, preventing the loss of information that a poll-based monitor might miss
This is the focus of proactive monitoring. It is also the predifined reason, SREs monitor their systems.
service-level objectives (SLOs)
In a monitoring query engine, this is the function of 'Filtering'
Selecting only the datapoints from a complete dataset that match specific conditions, such as a metric name or hostname.
This is why "Collaboration" is essential when monitoring a distributed microservices architecture
Teams must work together to pinpoint the source of problems in loosely coupled systems with dependent components.
What does the 'I' in TICK Stack stand for?
InfluxDB
This is a term for monitoring user behavior, page load times, and mobile crash information using web analytics
User Experience monitoring.
This is the size that Write Ahead Log (WAL) segments are typically stored
128 MB
These are three examples of statistical functions used during the 'Aggregation' phase of data analysis.
SUM, AVG, and MAX
This open-source tool is typically integrated with Prometheus to provide advanced dashboards and visualization?
Grafana
What does the 'C' in TICK Stack stand for?
Chronograf
This is how AIOps help reduce "noise" for Site Reliability Engineers (SREs)
It prioritizes alerts and focuses on critical issues by correlating related incidents.
This is what the fundamental building blocks of a Grafana dashboard is called
Panels
This visualization type is most effective for spotting outliers by joining data points to show a trend over time
Line Graphs
This is a cumulative metric that only increases or resets to zero on restart.
Counter
What is the main architectural change in InfluxDB 2.0 compared to the original TICK stack?
The separate components were merged into a single binary.
This Kubernetes component is responsible for deciding which containers go into which worker nodes
kube-scheduler
This is the typically amount of write operations in a monitoring system database
90%−95%
This is the negative consequence of an operations team setting 'too conservative' alerts
It leads to a deluge of notifications and 'alert fatigue', causing teams to ignore critical issues.
This is the period Prometheus stores collected time-series data locally in blocks of what duration
2 hours
In the Prometheus `prometheus-configmap.yaml`, what does the `scrape_interval: 15s` setting define?
The frequency at which Prometheus will pull metrics from its targets.
This is the smallest deployable unit in Kubernetes that shares the same host, IP address, and storage.
Pod
In a TSDB, this is 'downsampling' which is also known as 'data rollup'
The process of aggregating high-precision older data into fewer samples with lower granularity to save storage.
This is the primary benefit of 'Auto-rollup' features in databases like InfluxDB
They automatically perform downsampling without the need for the user to run explicit manual queries.
This is the purpose of the Write Ahead Log (WAL) in Prometheus storage?
To maintain a log of data that hasn't been persisted yet, allowing it to be replayed if the server fails.
these are the default 'first-time' login credentials for Grafana
