5xx server errors continuous monitoring

5xx server errors continuous monitoring is an ongoing (monthly) service: we continuously track server errors (500 Internal, 502 Bad Gateway, 503 Service Unavailable, 504 Gateway Timeout and others) — from server logs (if access is available) and/or regular synthetic requests to key URLs. We show: which pages and endpoints return 5xx, which codes, how often, spikes after a deploy or under load, and send an alert. This helps catch both one-off failures and systematic ones (e.g. a specific endpoint consistently failing, or 503s at peak hours from a lack of resources). Honestly about the essence: this is detection and alerting, NOT fixing — we do not fix code, configure the server or scale infrastructure for you; remediating the cause (a code bug, lack of resources, a wrong config, a failing third-party service) is done by your team, DevOps or by us separately. Monitoring only reports the problem faster and gives facts for the investigation. And honestly about coverage: logs show real user errors, but without log access synthetic requests catch only what falls into the check at the moment of the check — short or rare failures between requests can be missed. This is not a stability guarantee and not an SLA. Honestly about accuracy: both missed errors and false alerts are possible — we tune thresholds and filters, but 100% accuracy does not exist. Synthetic checks may rely on third-party services with their frequency limits and cost — we warn about that separately. Coverage is the configured URLs/sources; someone must react to an alert. An important boundary: this is 5xx monitoring, not development, not server configuration, not load testing and not APM (there are separate services for deep performance diagnostics). If the site is simple, on reliable hosting and with almost no logic, continuous 5xx monitoring may be overkill. Picture this: instead of "checkout periodically fails with 502, customers cannot pay, and you learn from complaints" you get an alert with the URL and code at the moment of the failure and see that 502s grow under load. The base price starts from 7,000 ₽ per month; it depends on the number of URLs and data sources.

• The server periodically returns 500/502/503/504 and you learn from customers.
• You do not know which pages and endpoints fail and how often.
• After a deploy server errors grow, but it is not noticed right away.
• Under load the site throws 503s, and it is unclear when and why.

• Tracking 5xx (500/502/503/504 etc.) from logs and/or synthetics
• Which URLs and endpoints return errors and which codes
• Frequency and spikes after a deploy and under load
• Distinguishing one-off from systematic failures
• Alerts at the moment errors appear
• Facts for investigating the cause (without the fix itself)
• Monthly continuous operation
• An alert channel of your choice (email, messenger, webhook)

• You learn about server errors first, not from complaints
• You see which URL, code and how often it fails
• You catch a 5xx rise after a release or under load earlier
• You have facts for the team to remediate the cause (the fix — separately)

• We clarify the sources (logs/synthetics), key URLs and alert channel; collect access
• We set up continuous 5xx tracking and spike thresholds
• We launch monitoring, send alerts and an error summary

• Will you fix the server if it returns 5xx?

  No. We detect errors and notify with details, but we do not fix code, configure the server or scale infrastructure. Remediating the cause is done by your team, DevOps or by us separately; monitoring gives facts and speed, not the fix itself.

• Will you catch any failure?

  It depends on the source. Logs show real user errors. Without log access synthetic requests catch only what falls into the moment of the check — short or rare failures between requests can be missed. This is not an SLA and not a stability guarantee.

• How is this different from APM and a load test?

  APM is deep application-performance diagnostics (traces, bottlenecks), a load test is a one-time check under load. This monitoring is ongoing observation of the fact of 5xx and alerting. They complement each other, but they are different services.
