Overview

When a Spotter query runs slowly or times out, first determine whether its time range, source scope, or conditions are contributing to the delay. Change one item at a time and confirm that the revised search still includes the events required for the investigation.

This guide uses a firewall investigation to show how to establish a baseline, narrow the search, test conditions, measure performance, and validate the results.

Quick diagnosis

Before you begin

Open Spotter and save the original query before editing it. Record the exact start and end timestamps, time zone, approximate elapsed time, and outcome. Capture the full error if the search fails.

For example, an investigation may require firewall events involving destination IP 10.20.30.40:

index = activity
AND resourcegroupname = "Production_Firewalls"
AND destinationaddress = "10.20.30.40"

Replace the example group and field values with values confirmed in your environment. Keep a known matching event available so that performance changes can be checked against investigation accuracy.

A timeout can occur with or without partial results. Preserve the actual message shown. Partial results do not establish complete investigation coverage. The effective timeout depends on the deployment and configuration.

Step 1: Test a shorter search interval

Keep the query unchanged to isolate the effect of the time range.

UI element to change: the time-range selector. Keep query text and time zone fixed during this test.

Step 2: Confirm fields and source scope

Instead of searching all activity for an IP address, narrow the search to the type of source expected to contain the evidence. If you know the specific datasource, narrow it further using its resource group.

For example, suppose you are investigating 10.20.30.40 and expect the relevant events to come from Palo Alto firewalls. The following examples progressively reduce the search scope. Use the same short time interval for each test.

          A. Start with the broad free-text search

index = activity
AND "10.20.30.40"

This searches for the value across searchable activity content without identifying a source type or address field. It may include unrelated datasource types and matches where the IP appears in a different context.

         B. Narrow to the expected resource type

index = activity
AND resourcetype = "Palo Alto Next-Generation Firewall"
AND "10.20.30.40"

Added condition: resourcetype limits the search to the expected product/device type. Events from other resource types are excluded, reducing the population being searched.

Use the actual resource-type value from your environment.

         C. Narrow further to the expected datasource’s resource group

index = activity
AND resourcetype = "Palo Alto Next-Generation Firewall"
AND resourcegroupname = "Production_Firewalls"
AND "10.20.30.40"

Added condition: resourcegroupname restricts the search to the expected group within that resource type. Use this additional restriction when you know which configured datasource should contain the evidence. A group can contain multiple devices; it does not necessarily identify one firewall.

          D. Use the confirmed address field

Open a relevant event and check which field contains the IP address. If the investigation specifically concerns destination traffic, use:

index = activity
AND resourcetype = "Palo Alto Next-Generation Firewall"
AND resourcegroupname = "Production_Firewalls"
AND destinationaddress = "10.20.30.40"

Changed condition: destinationaddress replaces free-text matching with an exact match on the relevant field.

The progression is:

Each restriction can reduce unnecessary searching, but it also excludes data. Confirm that the selected type, group, and traffic direction preserve the investigation’s required events. If the direction is unknown, use the source-or-destination example below.

Step 3: Optimize conditions

Use precise conditions when the investigation supports them. Test their effect on the same interval; operator choice alone does not guarantee a particular execution time.

• Example of a broad account search

index = activity
AND resourcegroupname = "Production_Firewalls"
AND accountname CONTAINS "smith"

• More specific account search

index = activity
AND resourcegroupname = "Production_Firewalls"
AND accountname = "jsmith"

Clause to compare: accountname CONTAINS "smith" versus accountname = "jsmith". These searches are not equivalent: equality excludes other accounts containing “smith.” Adopt it only when the complete account value is the intended target.

Write the query with clear source scope and entity conditions. Do not assume that moving a clause earlier in the text forces a particular execution order. Use the search help and optimization guidance for the deployed release before applying specialized operators or syntax.

Step 4: Isolate conditions and OR groups

Test one change at a time using the same index, resource scope, fixed interval, and time zone.

• Test A — Exact destination:

index = activity
AND resourcegroupname = "Production_Firewalls"
AND destinationaddress = "10.20.30.40"

• Test B — Add the required partial account condition:

index = activity
AND resourcegroupname = "Production_Firewalls"
AND destinationaddress = "10.20.30.40"
AND accountname CONTAINS "smith"

• Test large OR expressions in groups

For a search requiring source-or-destination matches for two IP addresses, preserve the full original expression and test the address groups separately.

Group A:

index = activity
AND resourcegroupname = "Production_Firewalls"
AND (sourceaddress = "10.20.30.40" OR destinationaddress = "10.20.30.40")

Group B:

index = activity
AND resourcegroupname = "Production_Firewalls"
AND (sourceaddress = "10.20.30.41" OR destinationaddress = "10.20.30.41")

If separate searches are necessary, run every group across the complete required period and combine their event sets. Deduplicate events matching multiple groups; adding match counts can double-count them. Replacing OR with AND changes the query's meaning.

Step 5: Measure query performance

• Use Console to identify the search

Open Spotter's Console tab and locate the corresponding query using the available timestamp, query text, and reported matches. Use those records to correlate your tests. Measure elapsed time separately when Console does not display duration.

• Use execution reporting where available

Ask an administrator to locate Spotter Metrics → Execution Details Report in the reporting interface, where available for the release. Use the report's query identifier, user, timestamps, searched interval, and execution-duration fields to match successful test runs.

Confirm the report's retention and included execution outcomes in the documentation for your release. A failed or timed-out search may not appear. Preserve its query, interval, error, and observed duration directly from Spotter.

Workload, caching, and data volume also influence timing. A single faster execution is useful evidence, but does not establish that the changed clause caused the improvement.

Step 6: Validate investigation coverage

Successful optimization means: the query completes, required evidence remains present, and the full investigation scope is covered. One matching event verifies a useful sample; it does not by itself prove completeness.

When the search completes but results display slowly

Record execution completion separately from the time until events, sorting, or charts become usable.

If completion cannot be established, record the observed status and ask an administrator or Support to distinguish execution from display delay. For persistent display problems, include browser/version, affected views, screenshots, and separate execution/display timings. Avoid launching overlapping searches while results load.

Choose the next action if the query still fails

When to contact Securonix Support

Contact Support when a narrowly scoped known-data query consistently fails, several users are affected, previously working searches fail without an explained change, or display problems persist after execution completes.
