Cservenak, Tamas updated HTTPCLIENT-1448:
-----------------------------------------
Affects Version/s: (was: 4.2.6)
> Add context information to INFO level logging
> ---------------------------------------------
>
> Key: HTTPCLIENT-1448
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1448
> Project: HttpComponents HttpClient
> Issue Type: Improvement
> Components: HttpConn
> Reporter: Cservenak, Tamas
> Priority: Minor
>
> In Nexus MRM HttpClient4x is used as transport. Nexus is a proxy server,
> hence there is a lot of (independent) interaction of HttpClient4x with remote
> servers on behalf of incoming requests. HttpClient does some INFO level
> logging that in my opinion lacks some context. Typical example:
> {quote}
> 2014-01-14 12:31:17 INFO [qtp1303027754-18064]
> org.sonatype.nexus.apachehttpclient.Hc4ProviderBase$DefaultHttpClientImpl -
> I/O exception (org.apache.http.NoHttpResponseException) caught when
> processing request: The target server failed to respond

> "Muting" the logger category or raising level to WARN is not an option, as we
> do not want to "mute" whole HttpClient4x.
> This is emitted by DefaultRequestDirector at INFO level, but is merely a
> log-spam, as it does not offer much information about actual host/target
> causing it.
> I'd propose to equip these messages with some technical and contextual
> information. Patch will be provided in few.
> Note: another option would be to just "lower" these logs (or one of the two)
> to DEBUG level, and leave the "Retrying request" part but with target host
> added.
