Experienced users of the "Classic" Scalyr UI might want to check out Introduction to the New Scalyr UI.
Use the graph view to graph values in your logs, such as server response times or page sizes. You can graph values from an individual log, aggregate multiple servers / logs, and use search terms to narrow the log messages to graph. This page gives a quick introduction. For a detailed description of all the powerful features provided by the graph view, see Graphs Reference.
To graph the values in a field, find that field in the left sidebar of the log view. Click on the field name, and click the "Graph Values" button at the bottom of the pop-up panel.
The "Graph Values" button will appear only for fields with numeric values.
To graph the rate at which some event occurs, such as a certain error message, use the log view to search for that event. Then click the "Show Graph" button above the timeline chart near the top of the log view.
(1) To search for a specific word or phrase, type it here. This determines which log messages are reflected in the graph. Numbers, punctuation, or phrases must be enclosed in quotes. Sample searches:
|error||To search for a word or part of a word, just type it|
|"/blog"||Punctuation must be enclosed in quotes|
|"customer 1309"||Multi-word phrases must also be enclosed in quotes|
|userId = 1309||Matching on a parsed field|
|time > 0.5||Numeric comparison on a parsed field|
See Query Language Reference for a full description of the Scalyr query language.
(2) When you enter a search term, it’s packaged into a "chiclet". Click on the chiclet to edit your search, or click the 'X' to delete that term.
(3) Click here to specify the time range to graph. The following options will appear:
(3a) Click on a preset to quickly graph that time range.
(3b) Enter the start time for your graph. You can enter a time (e.g. 14:30 or 5:05 AM), a date (May 23), or date and time (5/14/2016 2:00 PM), using a wide variety of date and time formats. You can also enter shortcuts like "5h" to indicate five hours ago. See Time Syntax Reference for a complete list of options.
(3c) Enter the end time for your graph. You can use any of the formats supported by the Fromt time. You can also enter a shortcut beginning with + to specify the amount of time you'd like to search, e.g. +24h or +1d to graph a one-day period beginning at the From time.
(4) Use these buttons to move forward or backward one half-graph at a time.
(5) Use this button to view the raw log messages matching your search.
(6) Use these fields to graph data from a specific server or log file. You can use * as a wildcard at the beginning or end (but not the middle) of a name.
(7) This area lists the fields Scalyr's parser has found in the log messages matching your search. By default, it shows the most common fields, limited to the number that will fit in your window ("Top Fields"). Click the dropdown and switch to "All Fields" to view all fields; then use the Prev/Next buttons to navigate through the alphabetical list. The number next to each field indicates how many distinct values appear in that field. (If there are more than a few hundred distinct values, the number shown will be an estimate.)
Click on any field to view the most common values in that field:
You can click on any value to restrict your graph to log messages having that field value. For numeric fields, click the "Graph Values" button to display a graph of that field.
(8) This shows the name of the field you're graphing.
(9) Click "Break Down By" to create a breakdown graph. A breakdown graph shows a separate plot for each server, or some other field you choose. For instance, if you're graphing the number of errors on your site, a breakdown graph will show the number of errors on each individual server. See Graphs Reference for details.
(10) This area shows a graph of the specified field.
(11) This area lists the functions which you can select for your graph. Check one or more boxes to select different functions of the graphed field. Each function is documented in the Graphs Reference.
You can click and drag in the graph to select a time range. The legend then shows aggregate statistics for the entire time range. A "Zoom to selection" button will appear; click this button to zoom in to the selected time range.
(12) These statistics apply only when you have dragged to select a time range in the graph. They show how much the graph changes during that time range.
(13) Use the chart type drop down to select the type of chart you'd like to see. If you choose Stacked Bar Chart you'll also be able to select the time interval for the bars, e.g. 1 minute or 1 hour. If you have a graph with a huge difference between highest and lowest values you may want to switch to a logarithmic y-axis.
