Crawler Monitoring Alert System: Prometheus+Grafana Performance Kanban

Brothers in reptiles look over here! Hands on with a surveillance system to keep your job!

Recently, an e-commerce friend complained to me that their crawler program is not moving to be blocked IP, the data did not catch much, the operation and maintenance every day to work overtime to repair the machine. This scene is not particularly familiar? Don't panic, today to give everyone a trick, with thePrometheus+GrafanaPut up a monitoring watchdog and a reliable proxy IP service, and you're guaranteed to have a crawler program that's as stable as an old dog.

First, the three major pain points of crawler monitoring

1. IPs die fast.: Single-IP wildly brush the site, minutes to be blacklisted!
2. Responds like a snail: The program is still silly when the target site is pumped up, etc.
3. Abnormal non-alarm: The program crashed in the middle of the night, only to find out at work the next day

Focus on the IP issue here. I've seen people use free proxies before, and 8 out of 10 IPs didn't work. Later, I changedipipgoThe exclusive IP pool, the survival rate directly pull to 95% or more, how to operate the specific details later.

Second, the monitoring system to build a four-part

Step 1: Install Prometheus
Execute this string of commands on the server (remember to change to your IP):

wget https://prometheus.io/download/
tar xvfz prometheus-.tar.gz
. /prometheus --config.file=prometheus.yml

Step 2: Configure the collector

Step 3: Grafana Kanban Configuration
Import official template ID13659Then change the charts to your needs. It is recommended to putNumber of IP switchesrespond in singingRequest delayMake a graph and see unusual fluctuations at a glance.

Step 4: Proxy IP Integration
Recommended hereAPI interface for ipipgo, code example:

import ipipgo
proxy = ipipgo.get_proxy(
    type='https',
    type='https', region='us'
)
requests.get(url, proxies=proxy)

Three tips for Kanban design

1. Red, yellow and green warning: Color coding of normal/warning/fault conditions
2. Comparison of historical trends: Putting the day's data together with the same period last week
3. geothermal map: Shows the difference in success rates for IPs in different regions

To cite a real case: a cross-border e-commerce customer used our program, the IP troubleshooting time fromAverage 45 minutesshorten to5 minutes or less, relying on the real-time alarm function on the Kanban board.

IV. Frequently Asked Questions QA

Q: Why do I have to use a proxy IP?
A: Just like driving a car to change tires, crawlers have to change IPs for a long-lasting war. Especially withResidential agent for ipipgoThe camouflage is not easily blocked.

Q: How often is the monitoring data updated?
A: It is recommended to set 15 seconds collection interval, too frequent will affect the program performance, the interval is too long will miss the abnormal report.

Q: What are the exclusive advantages of ipipgo?
A: They have it at homeReal Life Housing IPThe company supports on-demand customization of geographic areas, and the success rate of API calls has reached 99.2%, which is the top level in the industry.

V. Guidelines for avoiding pitfalls

1. don't put Prometheus and the crawler on the same server, easy to fight for resources
2. When setting up alarm rules, remember to addDuration conditionsAvoid false alarms for occasional fluctuations
3. Periodic cleaning of historical data, it is recommended that 7 days of retention should suffice

A final piece of cold knowledge: usingDynamic port function of ipipgoThe first step is to realize the concurrency of multiple channels in a single IP, and this technique is used by many old birds. Specific operations can find their home technology to case documents, pro-measurement can enhance the 20% capture efficiency.
