我想将日志严重性与 Google Cloud Logging agent 一起使用和一个在 Compute Engine 上运行的 linux (Debian) 虚拟机。
Compute Engine 实例是一台 debian-9 n2-standard-4 机器。
我已经按照 the documentation 安装了 Cloud Logging 代理.
$ curl -sSO https://dl.google.com/cloudagents/add-logging-agent-repo.sh
$ sudo bash add-logging-agent-repo.sh
$ sudo apt-get install google-fluentd
$ sudo apt-get install -y google-fluentd-catch-all-config-structured
$ sudo service google-fluentd start
并根据this paragraph ,如果日志行是序列化的 JSON 对象并且选项 detect_json 设置为 true,我们可以使用日志严重性。
所以我记录了类似下面的内容,但不幸的是我在 GCP 中没有任何严重性。
$ logger '{"severity":"ERROR","message":"This is an error"}'
但我希望是这样的:
我不介意日志条目的类型是 textPayload 还是 jsonPayload。
启用 detect_json 的文件 /etc/google-fluentd/google-fluentd.conf
:
$ cat /etc/google-fluentd/google-fluentd.conf
# Master configuration file for google-fluentd
# Include any configuration files in the config.d directory.
#
# An example "catch-all" configuration can be found at
# https://github.com/GoogleCloudPlatform/fluentd-catch-all-config
@include config.d/*.conf
# Prometheus monitoring.
<source>
@type prometheus
port 24231
</source>
<source>
@type prometheus_monitor
</source>
# Do not collect fluentd's own logs to avoid infinite loops.
<match fluent.**>
@type null
</match>
# Add a unique insertId to each log entry that doesn't already have it.
# This helps guarantee the order and prevent log duplication.
<filter **>
@type add_insert_ids
</filter>
# Configure all sources to output to Google Cloud Logging
<match **>
@type google_cloud
buffer_type file
buffer_path /var/log/google-fluentd/buffers
# Set the chunk limit conservatively to avoid exceeding the recommended
# chunk size of 5MB per write request.
buffer_chunk_limit 512KB
# Flush logs every 5 seconds, even if the buffer is not full.
flush_interval 5s
# Enforce some limit on the number of retries.
disable_retry_limit false
# After 3 retries, a given chunk will be discarded.
retry_limit 3
# Wait 10 seconds before the first retry. The wait interval will be doubled on
# each following retry (20s, 40s...) until it hits the retry limit.
retry_wait 10
# Never wait longer than 5 minutes between retries. If the wait interval
# reaches this limit, the exponentiation stops.
# Given the default config, this limit should never be reached, but if
# retry_limit and retry_wait are customized, this limit might take effect.
max_retry_wait 300
# Use multiple threads for processing.
num_threads 8
# Use the gRPC transport.
use_grpc true
# If a request is a mix of valid log entries and invalid ones, ingest the
# valid ones and drop the invalid ones instead of dropping everything.
partial_success true
# Enable monitoring via Prometheus integration.
enable_monitoring true
monitoring_type opencensus
detect_json true
</match>
文件/etc/google-fluentd/config.d/syslog.conf
:
$ cat /etc/google-fluentd/config.d/syslog.conf
<source>
@type tail
# Parse the timestamp, but still collect the entire line as 'message'
format syslog
path /var/log/syslog
pos_file /var/lib/google-fluentd/pos/syslog.pos
read_from_head true
tag syslog
</source>
我错过了什么?
注意:我知道 glcoud workaround ,但这并不理想,因为它将所有内容都记录在“全局”资源类型下,而不是在我的 VM 中。
最佳答案
Logger使用syslog,syslog“解析时间戳,但仍然收集整行作为‘消息’”
如/etc/google-fluentd/config.d/syslog.conf 中所述
在您的情况下,您可以通过 streaming structured logs via structured-log files 使用日志严重性以 json 格式。
这是
的结果echo '{"severity":"ERROR","message":"这是一个错误"}' >>/tmp/test-structured-log.log
