System Log Parserの最適化分析タイプを使用したArcGIS Enterprise分析（初心者向け）

AaronLopez

System Log Parserの最適化分析タイプ

おそらくSystem Log Parser (SLP)を使用してログを読み取り、ArcGIS Enterpriseの使用状況を定量化することに慣れていると思いますが、この人気の無料ユーティリティには、作業をより簡単にし、分析をより強力にする比較的新しい機能があります。

この機能は、「Optimized」レポートオプションであり、GUIのAnalysis Typeの下にある新しいパラメーターです。ArcGIS Server (Web)、ArcGIS Server (File System)、Internet Information Services (IIS)、および Elastic Load Balancer (AWS)などのログクエリでは、現在これがデフォルトになっています。このオプションはCloud FrontおよびAzureログクエリではまだ利用できません。後方互換性のために、Simple、WithOverviewCharts、およびCompleteタイプはまだオプションとしてありますが、最高の分析体験のためには推奨されません。

GUIに表示されるOptimized Analysis Typeオプション：

コマンドラインからも利用可能

GUI（SystemLogsGUI.exe）はレポート作成に便利ですが、コマンドライン版（slp.exe）はSystem Log Parser分析の自動化に最適です。Optimizedレポートオプションは両方で利用可能です！

Optimizedレポートの起源

長年にわたり、SLPに対する最も要望の多い改善点の一つは、非常に忙しいサイトや長期間（数週間以上）のログ解析時に実行しているマシンの速度とメモリ使用量の改善でした。Optimizedレポートはこれら二つの問題に直接対応しています。パフォーマンスは明らかに高速化され、メモリ使用量は桁違いに低減されています。より広範囲の時間をより速く検索できることで、より多くのリクエストを分析できるため、より強力な統計処理が可能になります。

最良の結果を得るには、ArcGIS Server (File System)、Internet Information Services (IIS)またはElastic Load Balancer (AWS)ログクエリでOptimizedレポートを使用してください。ArcGIS Server (Web)ログクエリでもメモリ使用量の節約は可能ですが、大量のログをREST Admin API経由で取得する処理が依然としてパフォーマンス上のボトルネックとなっています。

Optimizedレポート内容

System Log Parserレポートはログから得られる値を主要な時間ベースのカテゴリにグループ化することに重点を置いています。異なるログソース（ArcGIS Server、IIS、またはELB）向けのOptimizedレポートには共通点がありますが、利用されたソースによって追加統計が含まれる場合があります。例えば、OptimizedレポートがArcGIS Server (Web)またはArcGIS Server (File System)ログクエリで使用された場合、待機時間、インスタンス作成時間、および到着時間が経過時間に加えて統計的に詳細に分解されます。

Hi Aaron,

is it possible to let the application (GUI version) persist Log Location and Report Folder? Every time I start the app, it has default values.

Thank you.

AaronLopez

Hello @notebooker,
In the System Log Parser GUI it is not possible to persist those values.

However, everything you can do in the GUI you can also accomplish in the command-line version, slp.exe.
With PowerShell (or bat) scripts, you could persist the necessary inputs and make the execution easier.

Hope that helps.

I generated reports successfully. However most tables are empty (such as users, waiting time, statistics.....). I have the ArcGIS log level set to INFO. Is it the problem? Should set to to higher level of logging?

Hello.

Do we know if there are any compatibility issues with this tool and the ArcGIS Enterprise 11.2 software?

I recently set this up and ran it on one of our servers, however it doesn't look like it is working properly.

It completed and shows a start time and end time for the query and timing for the Start/End Time for Data (Coordinated Universal Time), but it doesn't show a Start/End Time for Data (Central Standard Time), plus the Data TimeSpan value is 0 along with a lot of the other values from Unique Resources Requested down.

Am I not filling something out right or is there an issue with 11.2?

Thanks,

AaronLopez

Hi @ghaskett_aaic,
My guess is that your 11.2 Site and System Log Parser are fine.
There are two conditions that exist that can lead to the situation of the generated report listing 0 hits.

The LogLevel of ArcGIS Server is set to a value of either Warning, Error or Info
- The statistics in the System Log Parser report are based on elapsed time request entries, but this requires the LogLevel to be set to Fine
- Verbose and Debug work too but they not recommended for Production sites due to how much detail is recorded
There were no requests to the Site during the specified log query duration (e.g., 2024-03-01T10:21:57 through 2024-03-05T10:21:57)
- For a quick check, authenticate to the Site from the REST service endpoint, select a service, pan or zoom around a few times, then generated the report with an end time that includes those requests (e.g., end time = now)
- This report should include your requests that were just made to the Site

Hope that helps
Aaron

@AaronLopezI would appreciate it if you could suggest the following -

Is there a way to obtain usage statistics of vector tile service published on ArcGIS Server?
Has anyone created a script or notebook to collect a list of all the vector tile packages with their storage size and usage statistics?
Logs for map and vector tiles generated by publishing services on ArcGIS Server?
Logs for how many features were edited by the user?
Logs of how many vector or raster tiles were downloaded by the user.

AaronLopez

Hi @AnjulPandey,

Is there a way to obtain usage statistics of vector tile service?
There might be some usage statistics through the ArcGIS Web Adaptor access logs (IIS log), if it is available.
The information here would be counts (how many times was a vector tile service requested) and performance (how long were users waiting to down load the tiles). System Log Parser should be able to address this the the Internet Information Services Log Query capability.
Has anyone created a script or notebook to collect a list of all the vector tile packages with their storage size?
Not that I am aware of but I have not specifically looked for tools that address that functionality.
Logs for map and vector tiles generated by publishing services?
Is this similar to the first item? Are you after usage statistics or publishing statistics.
If so, System Log Parser would summarize requests for such data (usage and publishing) from the ArcGIS Web Adaptor access log.
But it is worth pointing out that for publishing statistics, only the job's GUID would be listed in the report.
Logs for how many features were edited by the user?
This is interesting. Would this be hosted feature services, traditional or both?
For traditional feature services, this might involve queries to the enterprise geodata to understand what, if anything has changed since the check.
Although I am not sure if any observability or reporting tools do this, I have not looked.
Assuming the edited data was through the applyEdits function of a feature service, System Log Parser would list if that method was called. Of course, this does not mean the data was changed...just that the applyEdits function was called.
Logs of how many vector or raster tiles were downloaded by the user?
Map, Vector and Raster tile requests through a web adaptor are reported like any other request. System Log Parser would be able to report on usage statistics (e.g., counts and performance) from the ArcGIS Web Adaptor access logs. But, these log sources do not typically record the ArcGIS User that made the request. So the "who" would not be available.

Hope that helps
Aaron
