We keep a database of instrumentation dashboards and offer mechanisms for exploring with rich deep queries or with simple queries that forward results to spreadsheets for further analysis.
Click on the desired link. A new tab will open to run the selected single-page application.
The __Explorer__ has four panels.
Explorer
Grammar －Enter PEG rules, one per line. Tab or otherwise loose focus to parse current list selection.
List － Click a dashboard title to apply the current parse to the dashboard's panels ⇒ targets ⇒ expr text.
Tree － See the parse tree with counts for matches (+) and fails (-) on each branch. Click branch labels to see match cases with the text matched highlighted.
Cases － See in turn compile and run parsing errors, samples of successful matches, and, any matches of the `other` production.
The Explorer retains your grammar in browser local storage. If you are new to exploring, this small grammar will tell you something interesting about any text.
line = (word / numb / punct )+ word = [A-Z-a-z_]+ numb = [0-9]+ ('\.' [0-9]+)? punct = .
The __Selector__ has two panels.
Selector
First － Select the dashboards of interest. See how many match before continuing.
Last －Select the dashboard properties to appear as columns. Click download to save the selected fields on your own computer as grafana.tsv.
The browser will pop up a download notification. Click open to view and explore further in a spreadsheet.

This is what an Explorer grammar might look like part way through development.
line = _ ('empty' / funct / math / other)+ funct = aggr / call / paren aggr = agop ( paren )+ call = word ( paren /cparen )+ math = value op funct paren = '(' span ')' _ span = (![\)\(] .)+ cparen = '{' cspan '}' _ cspan = (![\{\}] .)+ op = arith / logic arith = [*/+-] _ logic =( 'and' / 'or' ) _ agop = ( counter / gague) _ by? gague = 'sum' / 'max' / 'min' / 'avg' counter = 'irate' / 'rate' / 'count' by = ( 'by' / 'without' ) _ value = funct / digits word = letters digits? _ letters = [a-zA-Z_]+ _ digits = [0-9\.]+ _ string = (single / double / back) _ single = '\'' (!'\'' .)* '\'' double = '"' (!'"' .)* '"' back = '`' (!'`' .)* '`' other = (![a-zAZ] .)+ _ = [ \t\n]*
