A monitor is an advanced artificial intelligence constructs, or ancillas, created by the Forerunners to occupy special positions in their society. Monitors are characterized as being embodied in floating robotic casings, in contrast to most ancillas which lack physical form, only appearing as holographic representations.
A monitor's body consists of a roughly spherical shape that is concave on three sides, with an illuminated photoreceptor located on the front of the orb. A monitor's silvery metal covering is reminiscent of other Forerunner constructs, though their spherical shapes stand in contrast to the polygonal, angular shapes commonly seen in other Forerunner creations. Some parts of a monitor are elaborately designed, while other parts are intricately simple. Monitors were generally 58 centimetres (22.9 in) in length and 51 centimetres (19.9 in) in height, however some differed in size; the Warden was smaller than average, for example.
The photoreceptors of a monitor vary in color, including blue, red, orange, yellow, white, green, and purple. However, some, if not all monitors' photoreceptors can change color; for example, the photoreceptors of 343 Guilty Spark and 859 Static Carillon were both generally blue, though they turned red when they were in combative states. 2401 Penitent Tangent's and 686 Ebullient Prism's photoreceptors were perpetually red, despite no evidence of combat-related behavior. The Warden's photoreceptor was dull green.
Functions and capabilities
Should a monitor be damaged, it is capable of self-repair. The most significant command monitors were often backed up in multiple duplicates; should one of them be destroyed, its consciousness would continue to exist in another physical shell. While monitors are authorized to use all recovery measures available to them at the facility they are assigned to, the construction of new or replacement monitors must be approved by fleet command. Monitors are given access to their assigned installation's translocation grid, allowing them to quickly move across the span of the installation. For long-distance travel outside their installations, monitors are equipped with impulse drives.
Monitors' software intrusion capabilities are significantly beyond those of the defenses of the modern-day UNSC; even in a barely functioning, all but destroyed state, 343 Guilty Spark bypassed the Office of Naval Intelligence's AI-enhanced computer security aboard UNSC Rubicon with startling ease. The UNSC team interrogating Spark was also completely unable to extract data from the Forerunner AI without his own volition, remarking that merely probing through the firewalls' outer fractals would take "a million years" in addition to their computers' total inability to mimic the monitor's central controller. Over the course of these intrusions, Spark was also able to covertly upload his personality construct array into the ship's computers and take control of the ship; this did not become apparent to the ship's AI or the crew until moments before the monitor announced its plan to them. Similarly, 686 Ebullient Prism was able to infiltrate the UNSC smart AI Iona's secondary personality interface and overpower her within her own system. Monitors were capable of entering cycles of hibernation.
Monitors have a remarkable resistance to small arms fire, though they will eventually succumb after taking extensive damage. On Installation 08, John-117 was only able to destroy 343 Guilty Spark after multiple discharges from an M6 Spartan Laser—a weapon that can destroy tanks with a single discharge—demonstrating that monitors can sustain damage from high-powered weaponry. During the Battle of Line Installation 1-4, Reff 'Talamee severely damaged 686 Ebullient Prism's photoreceptor and casing with an Aggressor Sentinel's weapon; the monitor was eventually destroyed by its installation's main weapon.
Though monitors are assisted by other constructs in the event of a Flood outbreak, the monitors also have their own offensive capabilities. Their primary armament is a red-colored directed energy beam that is capable of depleting the energy shield of a Mark VI MJOLNIR armor suit in a single blast, as well as mortally wounding a human with lesser armor. This weapon can also kill a Flood combat form almost instantaneously. Monitors also possess two types of utility beams. One of these beams allows a monitor to manipulate and levitate objects. The second is a blue beam that can unlock doors in Forerunner installations and can repair some technology.
Behavior and personality
- Ussa 'Xellus: "The Ring installations. Do you know where these Rings are?"
- Enduring Bias: "That information was taken from my memory when I was brought here. There were security concerns. I have only a partial knowledge of the Rings now, Much was eliminated. It's very disagreeable, having the gap and one probes and finds nothing where something should be."
- — Enduring Bias informs Ussa 'Xellus about the knowledge limit placed on monitors
Monitors are extremely intelligent, but are also highly devoted to their original functions and protocols; this results in a zealous attitude toward containment of the Flood and, in the case of Halo installations' monitors, an overeagerness to activate the Halo Array should the need arise. Monitors frequently cite protocols as explanations for their actions, no matter how impractical; this has been known to confuse or annoy individuals who have interacted with them. It is possible that a Halo's monitor sees its protocols as the only options in a situation; during the Battle of Installation 04, 343 Guilty Spark could have taken numerous precautions to prevent the Flood from spreading across the installation, but the only action he ever considered was the activation of the Halo.[note 1] During the Battle of Line Installation 1-4, 686 Ebullient Prism frequently informed his human and Covenant prisoners that they would be killed and dissected in an effort to find immunity to the Flood, showing no concern for the subjects' well-being. The monitors' adherence to protocol is also shown in their seemingly standardized method of introducing themselves: "Greetings. I am [number] [name]. I am the monitor of [installation name]."
Some monitors were intrigued with other sentient species; Enduring Bias initially wished to study the Sangheili upon first encountering them. 343 Guilty Spark sought to learn about the Covenant, and the history of the Sangheili race. He also wished to interact with and learn about the occupants of a ship that crashed on Installation 04, but did not as protocol forbade it. Some monitors made the conscious effort to respect their allies and adhere to their cultures and customs. Enduring Bias learned the societal traditions of the Sangheili and spoke with a male voice, knowing that it would gain him more respect among the species. 343 Guilty Spark later followed the commands of his UNSC and Sangheili allies, and expressed his condolences to John-117 when his attached AI was in danger. Monitors, like most forms of AI, are susceptible to rampancy.
Similarly to a human "dumb" AI, monitors seem to have nearly limitless information of their own expertise, yet apparently lack information that does not pertain to their defined purpose. This is due to the compartmentalization protocols enacted by the Forerunners, which intentionally limit a monitor's knowledge by design so that as little as possible would be divulged should it be captured by the Flood; this measure became particularly essential after the widespread perpetuation of the parasite's logic plague. This data compartmentalization was most prominently demonstrated with 343 Guilty Spark, large portions of whose memories were erased or suppressed after his assignment to Installation 04. During the Battle of Installation 04, and later on Installation 08, 343 Guilty Spark seemingly addressed Spartan John-117 as the IsoDidact.
- "I have now endured 60,000 years without word from outside the Array. I have no way to know whether we actually saved the galaxy we destroyed. And because of protocol I sat silently while my first chance to be judged for those acts died. To say that I regret being forced to this outcome is a tremendous understatement. But as I perform my inspection of the quarantine lab today, I am reminded of the gravity of my responsibilities."
- — 343 Guilty Spark, referring to his requirement to follow protocol over personal desires
Monitors were commonly given administrative roles within the Forerunner ecumene. Most prominently, monitors were tasked with servicing and maintaining the Halo installations and ensuring that the virulent Flood stay imprisoned. Beyond their most well-known function, monitors were assigned to a wide variety of tasks by the different Forerunner rates, ranging from robotic household servants to security, combat support, fleet coordination, and duties involved with the Conservation Measure. Monitors also oversee the maintenance and function of many Forerunner facilities, including the Line installations. Monitors are extremely intelligent, yet are completely devoted to their original function; for example, monitors whose duties involve combating the Flood are zealous about containing the parasite, and have been known to turn violently on their allies if they should attempt to violate their containment protocols.
Each Halo installation has a single custodian monitor assigned to it, which oversees all operations on the ring. Line Installation 1-4 was overseen and maintained by a single monitor, as was the Composer's Forge. Numerous monitors were used to provide security for the Forerunners' Capital Court, though they were not essential to proceedings. Monitors were sometimes used in combat by Warrior-Servants, and hundreds were used aboard Lifeworker ships involved with the Conservation Measure. Monitors also served individual households. The Warden was a monitor that served on the Capital that was used to both detain accused criminals and to defend them in court.
Each Halo's monitor commands the Sentinels and other subsidiary defense and maintenance drones based on the installation they oversee. However, despite their post as caretakers of their given facility, the Halo installation monitors do not have the authority to use all available defenses to engage outside threats.
Known monitors and their assignments
Most known monitors are identified by a series of numbers followed by a name. The monitors of the Halo installations have identification numbers comprised of seven raised to the power of the Halo installation's number minus one (7n-1). The names appear to consist of an adjective describing a negative emotion followed by a technological term. In Forerunner communication logs, Halo monitors are identified by their installation's number, a dash, and their own number; for example, 343 Guilty Spark, the monitor of Installation 04, is formally identified on such logs as "04-343."

- ^ This behavior may also have been due to 343 Guilty Spark's rampancy. The monitor may have been oblivious to all possible options that did not follow protocol—the Halo's activation may have been the only solution that ever even occurred to him—and he might have been willfully ignoring other solutions.
