function::linuxmib_filter_key - Linux
Overview
The linuxmib_filter_key
command filters a LinuxMIB result set based on a KVP pair. It is used to extract specific information from the returned data, allowing for focused analysis and reporting.
Syntax
linuxmib_filter_key --key <key> [--negate]
Options/Flags
--key <key>
: Specify the key to filter by, using the LinuxMIB KVP format.--negate
: Invert the filter logic, excluding results with the specified key-value pair.
Examples
Simple filtering by key:
Filter results for any key containing the string "uptime":
linuxmib_filter_key --key uptime
Filtering with negation:
Exclude results with the key "load_avg":
linuxmib_filter_key --key load_avg --negate
Complex filtering using multiple keys:
Filter for results containing the key "cpu_time" and excluding those containing the key "load_avg":
linuxmib_filter_key --key cpu_time --key load_avg --negate
Common Issues
- No results: Ensure the specified key exists in the LinuxMIB result set.
- Invalid key format: Key-value pairs in LinuxMIB follow a specific format (e.g.,
key.subkey.subsubkey
). Use the correct syntax to filter effectively.
Integration
- Use with other Linux performance monitoring tools, such as
linuxmib_query
andlinuxmib_summarize
, to create custom reports and dashboards. - Integrate into monitoring scripts and frameworks to automate Linux system health checks and performance analysis.
