Last updated - 22 July, 2025

Overview

LogicMonitor returns status codes for Web Checks, SSL environments encountered during Web Checks, and Ping Checks. These are helpful when troubleshooting monitoring errors. The following tables list and describe the possible status codes LogicMonitor may return for each of these.

Web Check Status Codes

Status for Individual Checkpoint Locations	Description
1	Okay
6	DNS failure
7	Timeout – either: the initial connection was not refused, but it did not complete in a reasonable time (just silence); OR the initial connection completed and some part of response was received, but the rest was not received in a reasonable time
8	TCP connection refused – the client got explicit information that it could not connect as it was configured to do.
9	SSL issue
10	Authorization required
11	HTTP status unexpected – the returned HTTP status does not match the expected HTTP status codes specified in the Web Check configuration
12	The keyword specified in the Web Check configuration does not match the response
20	The request timed out while loading the full page contents
21	There was no response to the HTTP request
23	The page load time is longer than the maximum time (configured in the Web Check’s Alert Triggering settings).
Overall Status	Description

SSL Status Codes for Web Checks

SSL Status for Individual Checkpoint Locations	Description
1	Okay
15	All other SSL error conditions
16	The certificate chain is untrusted

18	Certificate is expired

Ping Check Status Codes

Status for Individual Checkpoint Locations	Description
1	Okay
6	DNS failure
8	TCP connection refused – the client got explicit information that it could not connect as it was configured to do.
24	Either: Any returned packet takes longer than the configured minimum allowed return time (eg. 550ms return time when the limit is 500ms); or The number of packets returned is less than the configured threshold (for example, 8/10 packets returned when the threshold is 90%) Note: Minimum return time and minimum return packet percentage are configured in the Alert Triggering area of a Ping Check’s configurations.
Overall Status	Description
