The Alicloud log service provides with Web and SDK flavor to operate log service and analyzie logs. To make it more convinient to do automation, we release this command line interface (CLI).
Alicloud log service command line console, support almost all operations as web. It also supports incomplete log query check and query cross multiple pages. It could even do project settings copy cross multiple regions.
- Support almost all 50+ REST API of log service.
- Multiple account support to support cross region operation.
- Log query incomplete check and automatically query cross pagination.
- Multiple confidential storage types, from file, commandline to env variables.
- Support command line based or file based inputs, complete formation validations.
- Support JMES filter to do further process on results, e.g. select specific fields from json.
- Cross platforms support (Windows, Linux and Mac), Python based and friendly to Py2 and Py3 even Pypy. Support Pip installation.
The CLI supports below operation system:
- Windows
- Mac
- Linux
Python 2.6, 2.7, 3.3, 3.4, 3.5, 3.6, PyPy, PyPy3
Run below command to install the CLI:
> pip install -U aliyun-log-cli
Note
On mac it's recommended to use pip3 to install the CLI.
> brew install python3
> pip3 install -U aliyun-log-cli
if you encounter errors like OSError: [Errno 1] Operation not permitted
, try to use option --user
to install:
> pip3 install -U aliyun-log-cli --user
Alicloud ECS which may have limited internet access
You could try the mirrors of local network provider, for Alicloud ECS, you can try below noe:
pip/pip3 install -U aliyun-log-cli --index http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
Since 0.1.12, we provide offline package for mac x64 and linux x64 platform.
Follow below ways to install it.
- download the package from release page
- unzip it to a local folder, like
cli_packages
, you can see some whl files inside it. - if you don't have pip, install pip first:
python pip-10.0.1-py2.py3-none-any.whl/pip install --no-index cli_packages/pip-10.0.1-py2.py3-none-any.whl
- install the CLI:
pip install aliyun-log-cli --no-index --find-links=cli_packages
- verify it
> aliyunlog --version
- Encoutering errr

when installing CLI:
> pip install aliyun-log-cli
Collecting aliyun-log-cli
Could not fetch URL https://pypi.python.org/simple/aliyun-log-cli/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) - skipping
Could not find a version that satisfies the requirement aliyun-log-cli (from versions: )
No matching distribution found for aliyun-log-cli
Solution: Please upgrade pip and retry:
pip install pip -U
- Cannot find command
aliyunlog
?
it's caused by the missing of shell of aliyunlog
, you could make one by yourself.
2.1. find python path:
for linux or mac:
which python
on windows, it's probably located in c:\PythonXX
(XX means version like 27 or 37)
2.2. create a shell script named aliyunlog
(on linux/mac) or aliyunlog.py
with below content and allow to execute it. And put it into PATH
folder:
#!<python path here with ! ahead>
import re
import sys
from aliyunlogcli.cli import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
sys.exit(main())
for linux or mac, it could be put under /usr/bin/
.
On Windows, it could be put under c:/windows
.
2.3. verify it
# linux or mac
> aliyunlog --version
# windows
> aliyunlog.py --version

Refer to below link to install python-devel via yun
, apt-get
or manually.
https://rpmfind.net/linux/rpm2html/search.php?query=python-devel
Run below command to get the full usage list:
> aliyunlog --help
Note: aliyun
command is deprecated to prevent conflict with Universal Ali-cloud CLI.
it will show the full usage.
Note aliyunlog
is recommended in case the aliyun
conflict with others.
Refer to Configure CLI.
- Normally case:
> aliyunlog log get_logs --request="{\"topic\": \"\", \"logstore\": \"logstore1\", \"project\": \"dlq-test-cli-123\", \"toTime\": \"2018-01-01 10:10:10\", \"offset\": \"0\", \"query\": \"*\", \"line\": \"10\", \"fromTime\": \"2018-01-01 08:08:08\", \"reverse\":\"false\"}"
- Input via file:
You could store the content of one parameter into a file and pass it via the command line with prefix
file://
:
> aliyunlog log get_logs --request="file://./get_logs.json"
the content in file get_logs.json
as below. Note: the \
is unnecessary to escape the ".
{
"topic": "",
"logstore": "logstore1",
"project": "project1",
"toTime": "2018-01-01 11:11:11",
"offset": "0",
"query": "*",
"line": "10",
"fromTime": "2018-01-01 10:10:10",
"reverse": "true"
}
-
Mandatory check: if one mandatory parameter is missed, it will report error with usage info.
-
Format of parameter's value will be validated. e.g. int, bool, string list, special data structure.
-
for boolean, it support:
- true (case insensitive), T, 1
- false (case insensitive), F, 0
-
String list support as ["s1", "s2"]
-
For operations like Create, Update and Delete, there's no output except the exit code is 0 which means success.
-
For operations like Get and List, it will output in json format.
-
For errors, it will report in json format as below:
{
"errorCode":"...",
"errorMessage":"..."
}
It's supported to filter output via JMES:
Examples:
> aliyunlog log get_logs ...
which outputs:
[ {"__source__": "ip1", "key": "log1"}, {"__source__": "ip2", "key": "log2"} ]
You could use below --jmes-filter
to break log into each line:
> aliyunlog log get_logs ... --jmes-filter="join('\n', map(&to_string(@), @))"
output:
{"__source__": "ip1", "key": "log1"}
{"__source__": "ip2", "key": "log2"}
You could use >>
to store the output to a file. or you may want to process the output using your own cmd.
For example, there's another way to if you may want to break the logs into each line. you could append thd command with a |
on linux/unix:
| python2 -c "from __future__ import print_function;import json;map(lambda x: print(json.dumps(x).encode('utf8')), json.loads(raw_input()));"
or
| python3 -c "import json;list(map(lambda x: print(json.dumps(x)), json.loads(input())));"
e.g.
aliyunlog log get_log .... | | python2 -c "from __future__ import print_function;import json;map(lambda x: print(json.dumps(x).encode('utf8')), json.loads(raw_input()));" >> data.txt
1. aliyunlog log <subcommand> [parameters | global options]
2. aliyunlog configure <access_id> <access-key> <endpoint>
3. aliyunlog [--help | --version]
There's also an alias aliyunlog
for the CLI in case the command aliyun
conflicts with others.
1. aliyunlog log <subcommand> [parameters | global options]
2. aliyunlog configure <access_id> <access-key> <endpoint>
3. aliyunlog [--help | --version]
Actually, the CLI leverage aliyun-log-python-sdk
, which maps the command into the methods of aliyun.log.LogClient
. The parameters of command line is mapped to the parameters of methods.
For the detail spec of parameters, please refer to the Mapped Python SDK API Spec
Examples:
def create_logstore(self, project_name, logstore_name, ttl=2, shard_count=30):
Mapped to CLI:
> aliyunlog log create_logstore
--project_name=<value>
--logstore_name=<value>
[--ttl=<value>]
[--shard_count=<value>]
All the commands support below optional global options:
[--access-id=<value>]
[--access-key=<value>]
[--region-endpoint=<value>]
[--client-name=<value>]
[--jmes-filter=<value>]

It will fetch all data when
line
is passed as -1. But if have large volume of data exceeding 1GB, better to useget_log_all
-
get_log_all
- this API is similar as
get_logs
, but it will fetch data iteratively and output them by chunk. It's used for large volume of data fetching.
- this API is similar as
-
get_histograms

pull_logs
-
pull_log
- this API is similar as

By default, CLI store erros or warnings at ~/aliyunlogcli.log
, it's also configurable via file ~/.aliyunlogcli, section __loggging__
to adjust the logging level and location:
[__logging__]
filename= # default: ~/aliyunlogcli.log, Rotated when hit filebytes
filebytes= # Deafult: 104857600 (100MB), file size of each log before rotation, Unit: Bytes
backupcount= # Default: 5, file backup file
#filemode= # deprecated
format= # default: %(asctime)s %(levelname)s %(filename)s:%(lineno)d %(funcName)s %(message)s
datefmt= # default: "%Y-%m-%d %H:%M:%S", could be strftime() compitable date/time formatting string
level= # default: warn, could be: info, error, fatal, critical, debug
