Análise do ArcGIS Enterprise com o Tipo de Análise Otimizado do System Log Parser (Iniciante)

Tipo de Análise Otimizado do System Log Parser

Embora você provavelmente esteja familiarizado com o uso do System Log Parser (SLP) para ler logs e ajudar a quantificar o uso do ArcGIS Enterprise, há um recurso relativamente novo nesta popular ferramenta gratuita que pode tornar o esforço mais fácil e a análise mais poderosa.

Esse recurso é a opção de relatório "Otimizado", que é um novo parâmetro na interface gráfica listado sob Tipo de Análise. Para consultas de log como ArcGIS Server (Web), ArcGIS Server (File System), Internet Information Services (IIS) e Elastic Load Balancer (AWS), agora é o padrão. Esta opção ainda não está disponível para consultas de log do Cloud Front e Azure. Para compatibilidade retroativa, os tipos Simple, WithOverviewCharts e Complete ainda são uma opção, mas para a melhor experiência de análise, eles não são recomendados.

A opção Tipo de Análise Otimizado mostrada na interface gráfica:

Um relatório em planilha do System Log Parser gerado usando a opção Otimizado:

Também Disponível pela Linha de Comando

A interface gráfica (SystemLogsGUI.exe) é conveniente para criar relatórios, mas a versão de linha de comando (slp.exe) é ótima para automatizar a análise do System Log Parser. A opção de relatório Otimizado está disponível em ambos!

Origens do Relatório Otimizado

Ao longo dos anos, uma das melhorias mais solicitadas para o SLP tem sido melhorar a velocidade e o uso de memória (da máquina que o executa) ao analisar logs para Sites muito movimentados ou grandes períodos de tempo (por exemplo, várias semanas ou mais). O relatório Otimizado aborda diretamente esses dois pontos. O desempenho é visivelmente mais rápido e o uso de memória é várias ordens de magnitude menor. Com a capacidade de pesquisar períodos maiores com execuções mais rápidas, estatísticas mais poderosas podem ser realizadas, pois o relatório pode analisar mais solicitações.

Para melhores resultados, use o relatório Otimizado com ArcGIS Server (File System), Internet Information Services (IIS) ou Elastic Load Balancer (AWS) em consultas de log. Economias no uso de memória ainda podem ser obtidas com consultas de log ArcGIS Server (Web), mas o ato de recuperar grandes quantidades de logs através da REST Admin API ainda é o gargalo de desempenho.

Conteúdo do Relatório Otimizado

Os relatórios do System Log Parser focam em agrupar os valores dos logs em categorias-chave baseadas no tempo. Embora o relatório Otimizado para as diferentes fontes de log (ArcGIS Server, IIS ou ELB) tenha algumas semelhanças, podem haver estatísticas adicionais dependendo da fonte utilizada. Por exemplo, se o relatório Otimizado foi usado para consultar logs ArcGIS Server (Web) ou ArcGIS Server (File System), tempo de espera, tempo de criação da instância e tempo de chegada serão detalhados estatisticamente além do tempo decorrido.

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

@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
