[英]Azure Service Bus Topic Requests vs Messages
I need help interpreting these graphs:我需要帮助解释这些图表:
It has 0 subscriptions.它有 0 个订阅。 Does this mean nothing is reading from this topic?
这是否意味着没有从该主题中读取内容?
Looking at the Messages graph, in the last 30 days, no messages have been received or read from this topic.查看消息图表,在过去 30 天内,没有收到或阅读此主题的消息。
Why are there 368 incoming and successful requests, if nothing is being written to/read from this topic?如果没有向该主题写入/读取任何内容,为什么会有 368 个传入和成功的请求?
This is an expected behavior for incoming requests.这是传入请求的预期行为。
Even though there are no messages sending to service bus
, the Scale Unit
(which hosts the service bus) will always send requests to service bus
for health check
/ polling
purpose(I'm not very sure about this, just a guess).即使没有消息发送到
service bus
, Scale Unit
(托管服务总线)也会始终向service bus
发送请求以进行health check
/ polling
(我对此不太确定,只是猜测)。
You can check this behavior by setting Diagnostic settings
for azure service bus
.您可以通过设置
azure service bus
的Diagnostic settings
来检查此行为。 For example, you can send the OperationalLogs
to azure blob storage
or azure log analytics
, then you can check the OperationalLogs
later.例如,您可以将
OperationalLogs
发送到azure blob storage
或azure log analytics
,然后您可以稍后查看OperationalLogs
。 Like below(here, I send the logs to azure blob storage
):如下所示(这里,我将日志发送到
azure blob storage
):
Then wait for a few minutes, go to the azure blob storage
-> find the container named insights-logs-operationallogs
which is auto-created, and it's structrue like SUBSCRIPTIONS / RESOURCEGROUPS / PROVIDERS / NAMESPACES / year / month / hour / day / hour
-> then there should be an append blob similar to PT1H.json
.然后等待几分钟,go 到
azure blob storage
-> 找到自动创建的名为 insight insights-logs-operationallogs
的容器,其结构类似于SUBSCRIPTIONS / RESOURCEGROUPS / PROVIDERS / NAMESPACES / year / month / hour / day / hour
-> 那么应该有一个类似于PT1H.json
的 append blob。 You can download it and check the logs there.您可以下载它并检查那里的日志。 The log looks like below:
日志如下所示:
Inside the log, you can see that the caller
rpfrontdoor continues sending requests to service bus
.在日志中,您可以看到
caller
rpfrontdoor继续向service bus
发送请求。
Added a detailed log message here:在此处添加了详细的日志消息:
