Visual Scheduling System: Scrapy Task Monitor Panel

When crawlers meet visual monitoring, it's a sure thing!

Crawler friends have experienced this scenario: the script is running and suddenly stuck, turn back to check the logs and found that the IP was blocked. What's even more devastating is that you may not even know which part of the process went wrong. This time you need toReal-time visibility of task statusThe monitoring system is like putting a car recorder on the crawler.

What exactly does a surveillance panel look at?

Let's start with a few key metrics, these must be able to be on the panelglimpse::
- Number of currently active proxy IPs (don't leave the pool empty)
- Chart of success rate of requests (sudden drop to check)
- Frequency of requests for each IP (to prevent individual IPs from being used too hard)
- Abnormal status code statistics (403, 429 are danger signals)
- Ranking of IP switching times (to find out which IP segments are most likely to be blocked)

The dynamic IP pooling service from ipipgo is recommended here, and theirIP Survival Rate KanbanIt can be directly connected to Scrapy, for example, when you see that the IP of a certain region is continuously failing, you can immediately block the region in the panel to avoid continuing to use the "poisoned" IP.

Smart Scheduling Tips for Proxy IPs

It's not enough to have surveillance, you have to have the systemMake your own decisions.. These three points are the most practical in the programs we do for our clients:
1. Stepped punishment mechanism - Suspended for 5 minutes for the first failed request, and directly blacked out for 12 hours for the second one
2. Regional flow balances - Don't fixate on a particular regional IP (especially when using ipipgo's domestic IP)
3. Adaptive switching threshold - Automatically adjust the frequency of IP change according to the response speed of the target website.

Practical tips for ipipgo

We've tested it in real life, and you have to pay attention to these two details with their agents:
- Sub-line warm-up - Enable IPs from different regions in batches, don't just throw them all in.
- Mixed Use Strategy - Pair long-lasting static IPs with dynamic IPs (static IPs are good for scenarios that require logins)

Special mention of theirAbnormal Flow FuseFunction. Once we had a crawler bug that caused crazy request sending, the system automatically cut off the IP supply, avoiding the whole IP pool being banned by chain of command.

Frequently Asked Questions QA

Q: How can I tell when it's time to change IP pools?
A: Look at two indicators: the average daily number of failures of a single IP is more than 3 times, or the success rate of the whole pool is less than 70% for 1 hour in a row

Q: How often is it appropriate to change the IP of ipipgo?
A: Regular collection is recommended to rotate in 30 minutes, and high-frequency access scenarios should be shortened to 5-10 minutes. They can set up automatic replacement rules in the background

Q: Can I still use an IP that has been blocked?
A: It is recommended to freeze for more than 24 hours. ipipgo's IP recycling system will be automatically processed, but important tasks are recommended to directly change the new IP segment

Finally, a real case: an e-commerce customer used our monitoring panel + ipipgo agent, crawler survival time from an average of 4 hours to more than 72 hours. The key is toLet the data speak for itself., staring at the volatility curve on the panel to make adjustments is much more reliable than patting your head and changing IPs.
